Note: Chemicals can present a variety of hazards. A good source of information on chemical hazards is the Sandia Chemical Information System (CIS). The CIS contains a database of Material Safety Data Sheets. In addition, the CIS contains lists of chemicals according to various hazard categories and can search chemical inventories according to the categories. The following are examples of some of these lists of chemicals. The user can consult the CIS for a complete list of such documents as needed.
These lists must be used with caution, because in general, exposure quantities or paths that produce the effects indicated are not included in the lists. These lists are intended to serve only as a preliminary source of information for evaluating laboratory risks. Additional factors, such as quantity of chemicals used, frequency and duration of use, physical and chemical properties, and exposure control measures need to be considered to determine the overall risk potential of a chemical.
This supplement governs the acquisition, storage, use, and disposal of hazardous chemicals for both the OSHA Hazard Communication Standard and the Laboratory Standard at SNL/CA. The intention of this document is to ensure that routine chemical operations at SNL/CA are conducted in such a way as to minimize the risk to Members of the Workforce, threat to the environment, and the generation of hazardous waste. This document supplements ESH100.2.IH.4, Evaluate and Control Chemical Hazards.
This document is not intended to provide all-inclusive requirements or guidance for chemical operations, but should be used in concert with other Sandia Requirements documents such as the ES&H Corporate Procedures.
This document governs the use of hazardous chemicals. This document does not govern the use of the following materials, equipment, or systems:
It is the joint responsibility of department managers and owners of chemical work areas to determine whether any specific operation requires an activity-specific Technical Work Document (TWD). Call the ES&H Hotline at 294-3724 or review ESH100.2.GEN.3, Develop and Use Technical Work Documents if assistance is needed.
For purposes of this document, Members of the Workforce are:
This section applies to all Members of the Workforce who handle chemicals at SNL/CA.
The Health and Safety Department (8517) is responsible for this document. Send suggested changes to Al Buerer, MS 9221.
The safe handling of hazardous chemicals is an individual responsibility. Management responsibility lies with department managers and with delegated individuals for a particular operation. All personnel must understand that chemical safety is an integral part of the job and not an optional function. There is no activity that is so urgent that it is necessary to compromise safety or to endanger the environment.
During any operation, anyone may question the safety of any aspect of an activity and may at any time request and be granted the immediate cessation of the activity. Such requests should be made to the department manager or person conducting the operation at that time. The department manager has the authority to make an initial evaluation and decision to stop or to continue the operation. However, the individual questioning the safety of the operation should contact their center director if the question is not resolved satisfactorily. If the operation is immediately dangerous to life or health, the individual questioning the safety of the operation is authorized to immediately terminate the operation in a manner that eliminates or reduces the hazard and does not introduce new hazards that are immediately dangerous to life or health.
Support regarding safe handling of chemicals as related to the OSHA Hazard Communication Standard and the Laboratory Standard at SNL/CA is available from the Industrial Hygienists in the Health and Safety Department, Organization 8517. The individual Industrial Hygienists provide this support based on specific building assignments. Contact the ES&H Coordinator for your Department or call the ES&H Hotline at 294-3724 as needed to obtain Industrial Hygiene support for assessing chemical hazards and controls.
Center directors have other specific responsibilities as indicated in ES&H Corporate procedures, and ESH100.2.IH.4, Evaluate and Control Chemical Hazards.
Laboratory owners and personnel who perform work in a laboratory that is designated as an OSHA Laboratory Standard location have other specific responsibilities as indicated in ESH100.2.IH.4, Evaluate and Control Chemical Hazards.
Non-casual visitors must meet site-specific training requirements for the Hazard Communication Standard or Laboratory Standard.
The Sandia Chemical Hygiene Officer is the SNL/NM Subject Matter Expert for ESH100.2.IH.4, Evaluate and Control Chemical Hazards. This position currently resides in the Industrial Hygiene Compliance Services and Radiation Protection Laboratories Department (4121).

Flash point - The minimum temperature at which a liquid gives off sufficient vapor to first form an ignitable mixture with the air near the surface of the liquid or within a test vessel.
Greenhouse gases - Gases that persist in the atmosphere and are implicated in long-term warming of the earth.
Hazardous chemical - A chemical for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. The term "health hazard" includes chemicals which are:
Health hazard - See the definition for "Hazardous Chemical."
IDLH - Immediately dangerous to life and health. The maximum concentration of an airborne chemical from which an individual could escape within 30 minutes without a respirator and without experiencing any escape-impairing or irreversible health effects.
Irritant - A chemical, which is not corrosive, but which causes a reversible inflammatory effect on living tissue by chemical action at the site of contact as a function of concentration or duration of exposure. A substance that produces an irritating effect when in contact with skin, eyes, nose, or respiratory systems.
Laboratory - (Applies to OSHA Laboratory Standard locations.) A facility where the "laboratory use of hazardous chemicals" occurs. It is a workplace where relatively small quantities of hazardous chemicals are used on a non-production basis.

This term is usually referred to as "threshold limit value (TLV)." DOE orders mandate adherence to ACGIH TLVs and OSHA PELs, whichever limit is lower.
Toxic - A chemical falling within any of the following categories:
Volatile organic compounds (VOCs) - These are gases or liquids and solids with high vapor pressure that could be released to the air. These materials are implicated in the formation of smog and elevation of near-surface ozone levels.
Water-reactive - A chemical that reacts with water to release a gas that is either flammable or presents a health hazard.
All personnel who are engaged in work that involves the handling of hazardous chemicals shall receive basic SNL training appropriate to their work in either a Hazard Communication Standard or a designated OSHA Laboratory Standard location. See the HAZ and LAB series of courses in TEDS Everyone, for a description of applicable training courses.
Work in an office environment which involves the "household use" of chemicals or the use of computers or printer toners for photocopiers and fax machines is governed by the Hazard Communication Standard. These personnel are only required to take the Hazard Communication Briefing included in the ES&H New Employee Orientation.
Additional training may be required depending on the exact nature of the hazards in a particular operation. For example, radiation safety training may be necessary to handle radioactive materials. Department managers shall be consulted for specific training requirements for personnel assigned to chemical work areas.
HR100.2.1, Identify and Complete Sandia Required Training for all Members of the Workforce.
Face and eye protection shall be provided and used where chemical splashes present a hazard. The minimum protection is safety glasses with full sideshields for use with small quantities of chemicals that are not highly toxic or corrosive. Chemical splash goggles (with indirect venting) or full face shields with safety glasses shall be used for eye protection when handling materials under the following conditions:
Note: Operations that generate aerosols may also require respiratory protection as described in this section below.
Appropriate gloves shall be worn when handling corrosives, irritants, sensitizers, toxic chemicals, particularly hazardous substances, or chemicals with unknown toxicological properties. Gloves should be available in appropriate sizes and materials for the work performed in the area. For guidance in selecting glove materials, consult an industrial hygienist in the Health and Safety Department (8517).
Laboratory coats or other appropriate protective clothing shall be used as appropriate.
A respirator shall be worn if exposure to chemicals will exceed the action level. Use of respirators shall conform to requirements of the Sandia Respiratory Protection Program and ESH100.2.IH.4, Evaluate and Control Chemical Hazards. (applies to designated OSHA Laboratory Standard locations). To become an active user of respiratory equipment, contact the respirator program administrator in the Health and Safety Department (8517). See ESH100.2.IH.3, Control Inhalation Hazards Using Respiratory Protection, for more information
Fume hoods shall be surveyed after installation and annually thereafter. Laboratory owners shall contact an industrial hygienist in the Health and Safety Department (8517) for the survey to be performed. For further information on laboratory ventilation and use of fume hoods, see ESH100.2.IH.15, Control Hazards Using Local Exhaust Ventilation and High Efficiency Particulate Air Filters, and ESH100.2.IH.4, Evaluate and Control Chemical Hazards (applies to designated OSHA Laboratory Standard locations).
Fume hoods shall not be used as storage devices for chemicals or equipment unless required for inhalation safety or allowed by the SNL ES&H Manual. Users shall ensure that:
Every chemical work area shall be evaluated to determine if an eyewash and/or safety shower is required. The requirements for eyewashes and safety showers are listed in ESH100.2.IH.13, Work with Injurious Corrosive Materials and Manage Safety Shower and Eyewash Use. Emergency eyewashes shall be flow tested on a weekly basis. Safety showers shall be tested monthly. Flow testing shall be documented, and documentation maintained for a minimum of 365 days.
Every chemical work area shall be equipped with a telephone or portable communication device such as a radio for emergency use. Telephones shall include stickers with the emergency number and room location.
If a chemical is hazardous (or sensitive), laboratory workers shall:
Personnel must be able to obtain the MSDS and inventory either by accessing the Chemical Information System (CIS), on Sandia's Internal Web at https://webprod.sandia.gov/CIS/svStartup, or by contacting the MSDS Helpline at 294-MSDS, or the ES&H Hotline at 294-3724.Further information regarding procurement of chemicals is available at the Procurement Card homepage and at the GSS Fisher chemical supplier information page.
When procuring chemicals, personnel should avoid ordering excess quantities. For hazardous materials, personnel should not feel constrained to order "catalog" quantities. Many chemical suppliers will supply specific amounts of such items. There will be a price premium, but that is preferable to the price for disposal of excess quantities. Chemical quantities on hand should be limited to the volumes necessary for one supply cycle. Personnel should check the Chemical Information System (CIS) to see if the chemical can be obtained from other onsite locations.
Most chemicals arrive through the Logistics and Procurement Department (8523) and are barcoded and inventoried before delivery to individual chemical work areas; thus chemical inventories are available for review by using the Chemical Information System.
No chemical should be accepted from a supplier if it is incorrectly labeled. The manufacturer's or importer's label must contain the following information:
See ESH100.2.OTH.1, Manage Fire Protection Requirements for Information
In addition, personnel ordering such chemicals shall ensure that any other legal restrictions associated with the use of a particular material are obeyed.
Upon receipt of any explosive chemical, personnel shall ensure that the:
Some chemicals are subject to degradation with time (see Attachment B [Word file/Acrobat file]) and storage of these materials shall be regularly reviewed by the user.
All liquid chemicals in quantities greater than one pint (or 500 ml) shall be placed in a spill tray when they are not in use. Solid chemicals do not require secondary containment provided that they are protected by some other manner against falling and breakage in an earthquake (see “Seismic Considerations,” below). Chemicals requiring secondary containment may be stored in manufactured and approved chemical storage cabinets; additional tubs, trays, etc. are not required if the chemicals are compatible.
Secondary chemical containers shall be labeled with the chemical name and appropriate hazard warning information. For more information, see ESH100.2.IH.4, Evaluate and Control Chemical Hazards.
Hazardous chemicals or materials stored in glass or other breakable containers shall be protected from breakage during earthquakes. Common methods include storage in cabinets with latching doors, in spill pans at lower locations, or on shelves equipped with earthquake strips, lips, rods, wires or other devices to prevent containers from falling.
A chemical storage shed should:
Stored chemicals should be examined at least annually for signs of deterioration or degradation of container integrity.
Carcinogens used in laboratories are a sub-set of chemicals defined by OSHA as “Particularly Hazardous Substances.” See Section 8.4 for a discussion of the use of these materials in laboratories.
OSHA carcinogens which are used in areas other than laboratories may require special controls and monitoring. Contact Industrial Hygiene for an assessment if these materials are used outside of laboratories.
Flammable chemicals shall be stored in a flammable storage cabinet. Contact the fire marshal in the Planning and Construction Management Department (8512) for guidance in the placement of flammable storage cabinets. Such cabinets are normally not vented, and vent bungs should be in place (where accumulating vapors pose problems, an industrial hygienist and the fire marshal in Department 8512 should be consulted).
Flammable solids (in amounts greater than two ounces) should be stored in a flammable storage cabinet that has been labeled "Flammable Solids."
Sensitive chemicals shall be stored in a locked storage cabinet, preferably separate from other chemicals. Labels should indicate the specific hazards of the contents and that the contents are "controlled."
Note: The provisions within this section contain information regarding the use of peroxidizable chemicals due to the high potential for adverse effects from inappropriate use and/or storage thereof. However, in certain applications, researchers may wish to operate beyond these requirements. An example would be storage of a compound within a sealed ampoule and/or under an inert atmosphere, thus prohibiting contact with air. In these situations, researchers should submit to ES&H for review, a new technical work document (TWD) or revise a current TWD through an Interim Change Notice, or submit an SWP that includes procedures and controls that will be followed to ensure the safety of personnel expected to use peroxidizable chemicals beyond the scope of this document.
Under certain conditions, a number of organic and inorganic chemical compounds used at SNL are capable of reacting with atmospheric oxygen to form peroxide compounds. Many of these peroxides are highly flammable and may explode if exposed to heat, mechanical shock, friction or light. Potential adverse health affects may result if one is exposed to these peroxides should a container rupture. Three lists of common peroxide-forming chemicals grouped by hazard mechanism are found in tables 2, 3, and 4. The SNL chemical inventory can be queried for these listed chemicals using the three CIS queries: Peroxidizable Substances, Peroxidizable Substances (Concentrated), and Autopolymerizable Substances reports). While these are the most commonly encountered peroxide-forming chemicals, these lists are not all inclusive and do not contain all potential peroxide-forming compounds. Consequently, chemical users shall always consult individual MSDSs to ensure they are aware all chemical hazards. Peroxide-forming chemicals have different inherent potentials for forming peroxides, as designated by chemical groups, and therefore some are potentially more hazardous than others. Users can contact Waste Management on the ES&H Hotline at 294-3724 for guidance regarding questions related to peroxide formation.
Chemical owners and users shall be responsible for the safe use and storage of any chemical and especially peroxide-forming chemicals.
Chemical owners and users shall implement one or more of the following controls to minimize the formation of peroxides and to effect proper handling and storage:
Chemical owners and users having containers of peroxide-forming chemicals should dispose of them at or before their expiration date. Disposal must be through Waste Management. Contact Waste Management in a timely manner and complete a Peroxide Chemical Label when it is determined that it is necessary to dispose of the material.
Note: Suggested safe retention dates for chemicals are:
Chemical owners and users shall treat containers of peroxidizable chemicals that meet one or more of the criteria listed below as potentially explosive:
Members of the Workforce shall:
Special Storage: In rare circumstances, some of these materials are stored in special environments, such as under inert atmospheres to limit product degradation. In these cases, it may be permissible to retain these materials beyond normal retention dates, provided a knowledgeable owner can show that potentially dangerous levels of peroxides will not be formed.
Container disposal date is 3 months from open date.
Table 3. Chemicals that can form explosive levels of peroxides when concentrated
Table 4. Chemicals that may autopolymerize (and thus explode) when relatively
In addition, personnel shall follow these general procedures:
Every chemical work area shall have the appropriate Sandia ISMS sign on every entrance to identify specific hazards of materials contained therein. The names of responsible individuals shall be listed there.
All personnel shall conduct operations in a manner that minimizes the emission of all chemicals. Emissions are regulated locally by the Bay Area Air Quality Management District (BAAQMD). If operations that produce or may produce chemical emissions are underway or are being planned, personnel shall contact the Environmental Operations Department (8516) to determine if permits are required, or discuss this information during the Interdisciplinary Team (IDT) review for these operations. If a permit is required, operations shall not proceed until appropriate emissions logging procedures and reporting procedures are in place.
Particularly Hazardous Substances (PHSs) shall be handled and stored only in "designated areas." Personnel can determine if chemicals they use are included in these categories by accessing the Chemical Information System (CIS) report and selecting the “PHS” list for their query. A designated area may be an entire laboratory, an area of a laboratory, or a device such as a laboratory hood, or balance. The criteria used to determine the designated area may depend on the physical form (solid, liquid, gas), its physical properties, and the prevalence of use in the laboratory. Access to the designated area should be limited. Anyone working in the designated area must be aware of the substances being handled and the precautions that are necessary.
Laboratories, or areas within laboratories, which are designated areas shall be clearly posted using the ISMS sign or equivalent.
Storage areas shall be clearly labeled with appropriate warning signs that indicate the hazard. Containers that are used for carcinogens shall be so labeled.
To minimize the potential for contamination, laboratory workers who work with particularly hazardous substances shall:
Laboratory workers must decontaminate affected surfaces within designated areas in response to small spills or when the designated area (including contaminated equipment) is returned to general use. Personnel performing these decontamination activities must wear appropriate personal protective equipment to avoid exposure through skin contact or inhalation and must dispose of all wastes appropriately. The following are guidelines for the decontamination of liquids and powders. Consult the Material Safety Data Sheet for further information.
Work with particularly hazardous substances may require personnel to enter a medical surveillance program. See HR100.4.7, Participate in Medical Monitoring/Surveillance for further guidance. Personnel should contact the Health Services Department (8527) or their department manager for details.
Use of sensitive chemicals (drugs or drug precursors) should be held to a minimum. These chemicals may be controlled or illicit drugs or precursors that could be illegally used for the manufacture of such drugs. The primary concern with these chemicals is illegal use rather than chemical safety per se. Their use requires an active inventory procedure. All withdrawals from stock shall be noted and the notation signed by the person making the withdrawal. Department managers shall be responsible for an annual physical verification of inventory and records. Other legal restrictions may also apply to the use of certain sensitive chemicals. Loss or theft of these chemicals can result in serious penalties. Members of the workforce must consult the following before ordering sensitive chemicals:
US Department of Justice Requirements:
California State Requirements:
Personnel should purchase only pressurized containers that can be returned to the vendor. If this is impossible, personnel should contact the Environmental Operations Department (8516).
Generation of mixed chemical and radioactive waste requires prior approval from the vice president. Contact the Environmental Operations Department (8516) for information on this approval process. Precautions shall be taken in all operations to avoid the generation of mixed waste.
Chemical containers for chemicals synthesized, formulated, or modified by SNL must be barcoded and labeled with the same information that is required for manufacturers' labels (see "6.2 General Procurement Guidelines").
For chemicals synthesized on site, labels should indicate the date prepared and the name of the person responsible for the item. The originator should include as much information about the identity of the item (and its hazards) as possible, including lab references to lab notebooks, where appropriate. The same labeling requirements apply to unknown materials provided for chemical analysis. Personnel should not accept unknown materials/chemicals unless they are properly labeled.
See ESH100.2.IH.4, Evaluate and Control Chemical Hazards, (applies to OSHA Laboratory Standard locations) for more information.
