DATA SHEETS

WHAT IS AN
1 of 25
MSDS
A Material Safety Data Sheet (MSDS) is a document that contains-
• Information on the potential health effects of exposure to chemicals
• Safe working procedures when handling chemical products
MSDSs-
• Are to be provided by Supplier’s with all deliveries
• MUST be Accessible to EVERYONE in the workplace
• Must be current
• Must be made available to attending physician in the event of exposure

DEFINITIONS
Auto ignition temperature: Lowest temperature at which it
spontaneously ignites in normal atmosphere without an
external source of ignition.
Flash point: Lowest temperature at which vapors of a
volatile material will ignite, given an ignition source.

DEFINITIONS CONT’D
Lethal Dose50 (LD50): The value of LD50 for a substance is the
dose required to kill half the members of a tested population.
TWA: An 8-hour Time-Weighted Average is the
concentration the average worker can be exposed during an
8-hour workday, day after day, without harmful effects.

 MSDS’s are NOT Risk Assessments!
 When using substances you must carry out a
risk assessment but use the information in
MDSD’s to help you.
 Controls should be proportional to risk!
 Not all MSDS’s contain complete
information, although they should have!
 If in doubt, always use or consult an
expert.
REMEMBER!
