[PPT] Material Safety Data Sheet (MSDS) and it's 16 Section Training Document
Material Safety Data Sheet is Horoscope of the Chemical.
MSDS Reveals the
properties of chemical, its nature, different hazards, preventive measures in
storage & handling, First Aid measures.
It has 16 (Ten)
sections
•Threshold
Limit Value-Time-Weighted Average, TLV-TWA -- Time-weighted average concentration for an 8-hour workday
and a 40-hour work week in which a worker may be repeated exposed without
adverse health effects.
•
•Threshold
Limit Value-Short-Term Exposure Limit, TLV-STEL -- This is the maximum concentration
which workers can be exposed for 15 minutes
continuously without
adverse health affects. Only four of these 15-minutes exposures are permitted
per day and must have 60 minutes between exposures. The TLV-TWA still must not be exceeded.
•
•Threshold
Limit Value-Ceiling -- This is a defined boundary unlike TLVs which are
guidelines. It is the concentration which should never be exceeded at any
time during the working exposure.
•
•Permissible
Exposure Limit, PEL -- This is one of the most important OSHA limits used. It is
defined as the allowable limit for air contaminant in which workers
may be exposed day after day without adverse health effects.
