5) Fire Fighting Measures

General

Information:

As

in

any

fire,

wear

a

self-contained

breathing

apparatus

in

pressure-demand, MSHA/NIOSH (approved or equivalent), and full

protective gear.

During

a

fire,

irritating

and

highly

toxic

gases

may

be

generated

by

thermal

decomposition or combustion. Wear appropriate protective clothing to prevent contact

with

skin

and

eyes.

Wear

a

self-contained

breathing

apparatus

(SCBA)

to

prevent

contact with thermal decomposition products.

Extinguishing

Media:

Substance

is

noncombustible;

use

agent

most

appropriate

to

extinguish surrounding fire. Do NOT get water inside containers. Use water spray, dry

chemical, carbon dioxide, or appropriate foam.

personal

protective

equipment

as

indicated

in

Section 8.

Spills/Leaks:

Vacuum

or

sweep

up

material

and

place

into

a

suitable

disposal

container.

Clean

up

spills

immediately,

observing

in

the

Protective

Equipment

section.

Avoid

generating

dusty

conditions.

Provide

ventilation.

Place

under an inert atmosphere. Do not get water inside containers.

7) Handling and Storage

Handling:

Wash thoroughly after handling. Use with adequate ventilation. Minimize

area

away

from

incompatible

substances. Keep away from strong acids. Do not expose to air. Store protected from

moisture. Store under an inert atmosphere.

8) Exposure Controls, Personal Protection

Engineering Controls:

Facilities storing or utilizing this material should be equipped

with

an

eyewash

facility

and

a

safety

shower.

Use

adequate

ventilation

to

keep

airborne concentrations low.
