***This could be you . . .***

*A laboratory worker spilled an unknown chemical and the facility was
evacuated, causing lost work time for several employees.*

*An employee was exposed to a hazardous material. The MSDS wasn't
immediately available for hazard information, causing medical treatment
to be delayed.*

# 1. Applicability of this chapter

You are required to follow this chapter if you work at JSC or a JSC
field site. You are required to follow this chapter if you store, use,
or dispose of hazardous materials at JSC. If you work at WSTF, follow
WSTF requirements that meet the intent of this chapter.

# 2. What this chapter covers

This chapter is JSC's written hazard communication program to meet OSHA
29 CFR 1910.1200, "Hazard Communication Standard." This standard
requires JSC to inform workers of the hazards of the materials that they
work with or exist in their work areas.

Determining hazards

# 3. How JSC uses supplier information to determine hazards

JSC rarely makes hazardous materials. We rely almost entirely on MSDSs
from manufacturers and suppliers and give them a unique JSC MSDS number.
JSC organizations complete hazard assessments as necessary to identify
and control risks. Supervisors shall provide information on any new
hazards to their employees through training, instructions, safety
alerts, etc.

# 4. Assessing the hazards of hazardous materials

JSC determines hazards through hazard assessments using system safety
techniques as described in Chapter 2.4, "Hazard analysis."

You shall follow these guidelines for hazard assessments for the purpose
of this written program:

a.  Classify all hazards as physical or health hazards (see definition
    in the Glossary).

b.  Use, as baselines, any technical information from the supplier
    including MSDSs and any pertinent information from the sources in 29
    CFR 1910.1200.

c.  If an MSDS does not exist, consider any scientifically valid study
    that supports its classification as hazardous or establishes
    materials as being nonhazardous.

# 5. Reporting additional hazards you identify with hazardous materials

When you identify a hazard that isn't in the MSDS, you shall submit a
report detailing the hazard in question, the source of the information,
an analysis of potential impacts, and what you recommend to reduce risk.
Also, include any specific informa­tion that may refute your hazard
determination. When you have conflicting information, attempt to compare
the technical merits. Your management may submit the report without a
conclusion to the following organizations within 30 days of completing
the hazard assessment:

a.  Clinic Services Branch

b.  Safety and Test Operations Division

# 6. Mixing hazardous materials

When you mix "as-received" hazardous materials with other materials for
later use, you shall do a hazard assessment as described in paragraph 4
of this chapter to assess the possible hazards of the mixtures.

# 7. Assessing the hazards of a mixture

You may test the mixture as a whole to determine its hazardous
characteristics. You need to base all hazard assessments on positive
data that either establish or refute the mixture as hazardous. You shall
follow these requirements:

a.  If you don't test the mixture as a whole, you shall:

```{=html}
<!-- -->
```
1.  Assume that the mixture has the same health hazards as its hazardous
    components present in concentrations greater than 1.0% by weight or
    volume for non-carcinogens.

2.  Assume that the mixture has the same health hazards as its hazardous
    components present in concentrations greater than 0.1% by weight or
    volume for known or suspected carcinogens. You shall still identify
    known reaction products that are not present in the original
    components.

3.  Use relevant and scientifically valid data in place of testing to
    support any assessment of the physical hazards of the mixture.

4.  Indicate, in the hazard assessment, the lack of this information.

```{=html}
<!-- -->
```
b.  You shall document the results of the hazard assessment so you can
    later share it with all potential users. If you create the mixture,
    you are responsible for a complete and accurate hazard assessment.

c.  The Clinic Services Branch, the JSC Environmental Office, and the
    Safety and Test Operations Division shall review and approve initial
    shipments and accompanying documentation of such hazardous
    materials.

d.  You shall provide the percentage of each component in the mixture
    and an MSDS for each component with each shipment.

e.  You shall assume that the mixture poses the same hazards as each
    component, regardless of any prior or existing hazard assessments or
    test results, if someone using the mixture could be exposed to
    concentrations of any hazardous component above the OSHA- or
    ACGIH-permissible exposure limits.

# 8. Investigating and studying material exposures

The Clinic Services Branch shall conduct investigations and studies of
material exposures you need in your work area. This includes sampling
the concentration in the atmosphere to determine employee exposure
levels.

Hazardous materials inventory

# 9. Why JSC needs a hazardous materials inventory

The JSC Hazardous Materials Inventory allows for periodic review of all
hazardous materials on site. The JSC Hazardous Materials Inventory meets
the similar requirements of both EPA Superfund Amendments and
Reauthorization Act (SARA) and the OSHA Hazard Communication Standard.
The Clinic Services Branch maintains JSC's inventory with inputs from
the organizations.

# 10. How to use the hazardous materials inventory

This inventory reflects the hazardous materials in your work area. The
following requirements apply:

a.  All employees in your work area shall have access to the inventory.
    You may use the inventory as a guide to make sure that all MSDSs you
    need are available.

b.  You shall keep the hazardous materials inventory at specific
    worksites in accordance with directorate instructions.

c.  Someone in your area shall be responsible for updating the inventory
    whenever you get a new product, when you remove an old product, or
    when there is a significant change in the quantity of the product.

d.  You shall enter new materials into the inventory when you first
    receive them.

# 11. Contents of a hazardous materials inventory

The following requirements apply to your inventory:

a.  Your inventory shall include, as a minimum, the identity of the
    materials, as written on the label; the JSC MSDS numbers; the
    location of the materials; the amount usually kept on hand; the
    largest amount ever present in the workplace; and the quantity used
    annually.

b.  You shall specify the locations in enough detail to allow someone to
    find the materials quickly.

c.  If you run out of materials meant for replenishment, they shall
    remain on the inventory.

d.  If you don't anticipate replacing them, you shall remove the
    materials from the inventory before the next annual update.

e.  The inventory shall include all hazardous materials under the
    control of your area.

# 12. What you should do if you are responsible for entering your area's items into the inventory

Each area needs to have someone responsible for evaluating the hazardous
materials inventory for that location. If you are responsible for
maintaining hazardous materials inventory for your work area, you shall:

a.  Contact the Occupational Health Department to get a user code and
    password for your inventory.

b.  Enter all items into the on-line inventory available on the Health
    Homepage.

c.  Continue to list on the inventory any materials you run out of but
    plan to replenish or continue to use. Delete items no longer in
    stock that you no longer plan to use.

d.  If a material has not been used during the past year, you should
    consider excessing the item.

e.  Get JSC MSDS numbers for all items and record the numbers in your
    inventory.

f.  Review and correct the inventory at least yearly or whenever
    quantities or locations change significantly. Some products require
    quarterly updates.

g.  Compare incoming materials with the hazardous materials inventory to
    screen for new chemicals.

**Note**: You can find additional directions for updating the hazardous
materials database in the HazMat Inventory Users' Guide located at:
<http://sd.jsc.nasa.gov/omoh/scripts/OccupationalHealth/MSDS.aspx>

# 13. Access to the inventory

Each directorate shall make sure that:

a.  All directorate activities, facilities, and employees related to
    hazardous materials are completely addressed.

b.  All employees have access to hazardous materials inventory, MSDSs,
    and a copy of this chapter during their shift.

c.  Employees keep their area hazardous materials inventory up to date
    in the on-line master site inventory.

# 15. Exemption of wood and wood products 

Wood and wood products are exempt in full from this chapter.

# 16. Articles other than raw chemicals

You shall follow these steps to determine whether an article will be
considered as a hazardous material:

a.  First determine whether the item meets the definition of an
    "article" under 29 CFR 1910.1200. If any item meets all of these
    criteria, it is an "article" and exempt from the requirements of the
    Hazard Communication Standard:

```{=html}
<!-- -->
```
1.  It has a specific shape or design as a result of its manufacture.

2.  It has end-use function(s) that depend in whole, or in part, upon
    its shape or design during end use.

3.  It doesn't release, or otherwise result in, exposure to a hazardous
    chemical under normal conditions of use.

```{=html}
<!-- -->
```
b.  Assess the hazard potential for articles that fail to meet one or
    more of the criteria listed above.

c.  Consider the entire lifetime of the article, including initial
    fabrication, test, end use, maintenance, storage, demolition, and
    disposal. Review the results of these assessments at the appropriate
    review activities such as design reviews or TRRs. You shall have
    Safety and Occupational Health concurrence on the results of these
    assessments.

**Note**: Examples of articles that clearly fall under JSC's hazard
communication program are welding rods, metal stock, and many
construction materials (other than untreated wood).

Labeling and other forms of warning

# 17. Labeling storage and transportation containers

Follow these requirements for labeling storage and transportation
containers:

a.  You need to label all storage containers, tanks, vessels, drums,
    etc., meant for holding any quantity of hazardous materials for any
    period of time. The label shall include the following:

```{=html}
<!-- -->
```
1.  The identity of the hazardous material, identical to the trade name
    on the MSDS

2.  Hazard warnings

> The Clinic Services Branch will provide guidance in the design and use
> of hazardous materials labels or other means to warn users of physical
> and health hazards.

b.  When you use containers for transporting hazardous materials to or
    from JSC, you need to identify the containers. The DOT requires
    placards on containers (for example, truck, train car, etc.) of
    hazardous goods meeting certain type and weight requirements that
    are transported within the U.S. or on U.S. waterways. The
    identification shall include the following:

```{=html}
<!-- -->
```
1.  The name of the authorizing official, the assigned office, or
    element

2.  The address of the organization authorizing the shipment

```{=html}
<!-- -->
```
c.  You shall only use shipping containers with DOT approval specific
    for the material to be shipped.

# 18. Transfer containers

You don't need to label the containers that you use to quickly transfer
a material between containers. This exemption includes beakers, buckets,
funnels, portable pumps, and similar equipment. If you must stop your
transfer before it's complete, you shall secure the container per
acceptable procedures, temporarily identify its contents, and preferably
keep it near the original container.

# 19. Identifying pipeline, ducts, valves, etc.

You shall clearly identify:

a.  All pipes, ducts, valves, etc., that carry hazardous materials in
    any form or visibly connect to hazard­ous materials sources per
    Chapter 9.1, "Hazardous material safety and health," of this
    handbook.

b.  Pipes, ducts, etc., that connect to hazardous materials sources and
    don't carry the materials in a manner that is clearly visible to any
    observer.

```{=html}
<!-- -->
```
a.  The contents of pipes, ducts, etc., if you can't see their contents
    because of obstructions such as a wall or if they are underground.

b.  If the number or location of pipes, ducts, etc., in any area makes
    it difficult to identify each one, you may hang placards around the
    area or along its length. Placards may take the form of color
    coding, labels, or signs. You shall place placards according to
    their size, visibility, and the points of approach to the area.

Material safety data sheets

# 20. Availability of MSDSs

The following requirements apply:

a.  You shall be able to readily access MSDSs in your work area during
    your work shifts.

b.  Your supervisor shall maintain an up-to-date hardcopy file of MSDSs
    for hazardous materials that you use in your operations in a readily
    accessible location.

c.  All MSDSs in your work area shall have a JSC MSDS number. Replace
    any unnumbered MSDSs with numbered copies from Occupational Health
    Department. MSDS are also accessible on line through the Health Home
    page at
    <http://sd.jsc.nasa.gov/omoh/scripts/OccupationalHealth/MSDS.aspx> .
    See Chapter 9.1 of this handbook for ordering MSDS for hazardous
    materials used in your work area

shall meet the following:

a.  Everyone who works at JSC shall take initial and annual basic Hazard
    Communication (HazCom) training.

b.  Individuals who work with hazardous materials shall initially take
    instructor-led HazCom training. After taking an instructor-led
    class, you may take your annual training through the on-line HazCom
    training accessible on SATERN. Individual contractors may arrange to
    provide their own HazCom training as long as the training meets the
    requirements of 29 CFR 1910.1200 and this manual.

c.  If you work in an office environment, you may take both your initial
    and annual training through SATERN.

d.  If you handle or use hazardous materials, or work in an area with
    hazardous materials, you also need to get specific information and
    training on the hazardous materials in your work area. This shall be
    completed by your supervisor when you are first assigned, annually,
    and when new hazards or chemicals are introduced in your work area.
    Organizations may request substance specific training from the
    Occupational Health Department, x36726.

e.  Basic and specific HazCom training shall collectively explain:

```{=html}
<!-- -->
```
1.  The requirements of 29 CFR 1910.1200.

2.  Operations in your work area where hazardous materials are present.

3.  The location and availability of the written HazCom program, lists
    of hazardous materials, and MSDSs.

4.  Methods and observations to detect the presence or release of a
    hazardous material in the work area such as visual appearance or
    odor.

5.  Physical and health hazards of the materials in the work area.

6.  Measures you can take to protect yourself from these hazards. This
