INTRODUCTION TO MATERIAL SAFETY DATA SHEETS

WHAT IS AN

1 of 25

MSDSA 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 productsMSDSs-• 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!PLEASE
