, Q: specific gravity The ratio of the density of a material to the density of pure
water. A product
Answer:
with a specific gravity greater than 1 will sink in water; less than 1, it will float on
top of water.
Specific gravity is an important characteristic to consider when planning spill
cleanup and fire
fighting procedures.
coefficient of water/oil distribution Is a measure of the inability of a product to mix
with
water. It has significance in cleanup procedures.
flammability if a product belongs in Class B, the box "YES" on the MSDS must be
checked.
Conditions under which ignition could occur must be described. Flammable products
have a
flashpoint below 37.8 °C versus combustible products that have a flashpoint above
37.8 ° C.
means of extinction A list of extinguishing agents suitable for use on the burning
product.
special procedures If a product has unusual hazardous properties when it is involved
in a
fire, precautions for fire fighting must be described.
flashpoint and method the flashpoint is the temperature at which a liquid or volatile
solid
gives off enough vapours to form a flammable air-vapour mixture near its surface.
The lower
the flashpoint, the greater the fire hazard. Chemicals with flashpoints at or below
room
temperatures can produce enough vapours to cause an explosive atmosphere. The
