### Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water

spray to cool fire exposed con tainers and fire affected zone until fire is out and danger of reignition has

passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose

holders or monitor nozzles. Immediately withdraw all personnel from t he area in case of rising sound

from venting safety device or discoloration of the container. Do not use direct water stream. May

spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be

mo ved by flushing with water to protect personnel and minimize property damage. Contain fire water

run

- off if possible. Fire water run

- off, if not contained, may cause environmental damage. Review the

"Accidental Release Measures" and the "Ecol ogical Information" sections of this (M)SDS.

Inhalable

fraction and

vapor. 1 mg/m3 SKIN

A "skin" notation following the inhalation exposure guideline refers to the potential for dermal

absorption of the material including mucous membranes and the eyes either by contact with vapors or

by direct skin contact.

It is intended to alert the r eader that inhalation may not be the only route of exposure and that

measures to minimize dermal exposures should be considered.



### Personal Protection

Eye/Face Protection: Use safety glasses (w ith side shields).

Skin Protection: Wear clean, body

- covering clothing.

Hand protection: Use gloves chemically resistant to this material when prolonged or

frequently repeated contact could occur. Examples of preferred glove barrier materials

include: Butyl rubber. Natural rubber ("latex"). Neoprene. Nitrile/butadiene rubber ("nitrile" or

"NBR"). Polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Polyvinyl alcohol ("PVA").

Polyvinyl chlori de ("PVC" or "vinyl"). NOTICE: The selection of a specific glove for a particular

application and duration of use in a workplace should also take into account all relevant

workplace factors such as, but not limited to: Other chemicals which may be handled , physical

requirements (cut/puncture protection, dexterity, thermal protection), potential body reactions

to glove materials, as well as the instructions/specifications provided by the glove supplier.

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed

the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements

or guidelines, wear respiratory protection when adverse effects, such as respir atory irritation or

discomfort have been experienced, or where indicated by your risk assessment process. For most

conditions no respiratory protection should be needed; however, if discomfort is experienced, use an

approved air

- purifying respirato r. The following should be effective types of air

- purifying respirators:

Organic vapor cartridge with a particulate pre

- filter.

Ingestion: Use good personal hygiene. Do not consume or store food in the work area . Wash hands

before smoking or eating.



### Engineering Controls

Ventilation: Use local exhaust ventilation, or other engineering controls to maintain airborne levels

below exposure limit requirements or guidelines. If there are no applicable exposure limit

requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust

ventilation may be necessary for some operations.
