______________________________________________________________________________________________
Extinguishing media which must not be used for safety reasons
Water.

Specific Hazards Arising from the Chemical
Flammable. Containers may explode when heated. Water reactive. Contact with water liberates extremely flammable gases.


Protective Equipment and Precautions for Firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full
protective gear.

                       SECTION 6. ACCIDENTAL RELEASE MEASURES


Personal Precautions
Use personal protective equipment as required. Avoid dust formation. Remove all sources of ignition. Take precautionary
measures against static discharges.


Environmental Precautions
Should not be released into the environment. See Section 12 for additional Ecological Information.


Methods for Containment and Clean Up
Remove all sources of ignition. Do not expose spill to water. Sweep up and shovel into suitable containers for disposal. Avoid dust
formation. Use spark-proof tools and explosion-proof equipment.


Refer to protective measures listed in Sections 8 and 13.

                          SECTION 7. HANDLING AND STORAGE


Handling
Wear personal protective equipment/face protection. Avoid contact with skin, eyes or clothing. Avoid ingestion and inhalation. Avoid
dust formation. Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools. Use spark-proof
tools and explosion-proof equipment. Take precautionary measures against static discharges. Do not allow contact with water.

Storage
Keep containers tightly closed in a dry, cool and well-ventilated place. Flammables area. Keep away from heat, sparks and flame.
Keep away from water or moist air. Store under an inert atmosphere.

Specific Use(s)
Use in laboratories

                  SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Control Parameters



Monitoring methods
BS EN 14042:2003 Title Identifier: Workplace atmospheres. Guide for the application and use of procedures for the assessment of
exposure to chemical and biological agents. MDHS14/3 General methods for sampling and gravimetric analysis of respirable and
inhalable dust

Exposure Controls

Engineering Measures
Ensure that eyewash stations and safety showers are close to the workstation location. Ensure adequate ventilation, especially in
confined areas. Use explosion-proof electrical/ventilating/lighting equipment. Wherever possible, engineering control measures
such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact,
and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source.

of cuts, abrasion.
Remove gloves with care avoiding skin contamination.

   Skin and body protection      Wear appropriate protective gloves and clothing to prevent skin exposure

   Respiratory Protection       When workers are facing concentrations above the exposure limit they must use
                                      appropriate certified respirators.
                              To protect the wearer, respiratory protective equipment must be the correct fit and be used
                               and maintained properly

   Large scale/emergency use    Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits
                                    are exceeded or if irritation or other symptoms are experienced
                           Recommended Filter type: Particulates filter conforming to EN 143

   Small scale/Laboratory use     Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure
                                              limits are exceeded or if irritation or other symptoms are experienced.
                           Recommended half mask:- Particle filtering: EN149:2001
                           When RPE is used a face piece Fit Test should be conducted
