We use many chemicals… : 

We use many chemicals… We want you to know how to use them safely You will learn about… The Hazards of Chemicals Our Written Program How Chemicals are Labeled Safe Use of Chemicals Material Safety Data Sheets Basic Procedures for Spills Who you can ask for more information 6/28/2010 Eng. kamal Nashar 2

Hazards of Chemicals… : 

Hazards of Chemicals… There are 2 basic types of chemical hazards Physical Hazards Health Hazards The first rule of chemical safety is… "Know what you are working with and how to protect yourself and others“ 6/28/2010 Eng. kamal Nashar 3

Physical Hazards… : 

Physical Hazards… Chemicals are classified as having Physical Hazards if they are Explosive Compressed Gas Combustible Liquids Flammable Unstable Water Reactive Oxidizers 6/28/2010 Eng. kamal Nashar 4

Physical Hazards… : 

Physical Hazards… Some chemicals may be safe by themselves, but become dangerous when in contact with other substances. 6/28/2010 Eng. kamal Nashar 5

Chemicals with Physical Hazards… : 

Chemicals with Physical Hazards… Used only by trained employees Stored in a safe manner Never mixed with other chemicals unless by an approved procedure 6/28/2010 Eng. kamal Nashar 6

Health Hazards : 

Health Hazards Chemicals are classified as being a health hazard if they: Can cause cancer Are poisonous (toxic) Cause harm to your skin, internal organs, or nervous system Are corrosive - such as acids Cause allergic reactions after repeated exposure 6/28/2010 Eng. kamal Nashar 7

Chemicals can enter the body through: : 

Chemicals can enter the body through: your lungs if you breath fumes, mists or dust your skin if liquid or dust touches or spills on you or splashes in your eyes your mouth if you eat after handling chemicals accidental swallowing of a chemical 6/28/2010 Eng. kamal Nashar 8

Health Effects… : 

Health Effects… Some chemicals affect specific organs such as your kidneys, liver, reproductive or nervous system. 6/28/2010 Eng. kamal Nashar 9

Our Written Hazard Communication Program provides… : 

Our Written Hazard Communication Program provides… Written information on hazards Lists chemicals we use and their hazards System for ensuring chemicals are labeled Means to ensure we have an Material Safety Data Sheet (MSDS) for each chemical 6/28/2010 Eng. kamal Nashar 10

Our Written Hazard Communication Program… : 

Our Written Hazard Communication Program… Lists who is responsible for the program Provides chemical specific safety training methods Tells you where to find chemical safety information You can see a copy of our written program by asking you supervisor 6/28/2010 Eng. kamal Nashar 11

Labeling of Chemicals… : 

Labeling of Chemicals… Chemical labels provide information on Identity, Hazards and Safe Use All chemical containers are labeled by the manufacturer Our company may place additional labels on the containers 6/28/2010 Eng. kamal Nashar 12

Labeling of Chemicals… : 

Labeling of Chemicals… If chemicals are placed in another container, this new container must have a a label placed on it. All containers must be properly labeled 6/28/2010 Eng. kamal Nashar 13

Uniform Labeling System… : 

Uniform Labeling System… Our university “Uniform Labels” are used to ensure we have one labeling system. These may be placed on containers when chemicals are delivered to us or chemicals are transferred to other containers 6/28/2010 Eng. kamal Nashar 14

2 Basic “Uniform Labels” : 

2 Basic “Uniform Labels” HMIS - Hazardous Material Identification System NFPA - National Fire Protection Association Both types must identify the chemical name and hazards 6/28/2010 Eng. kamal Nashar 15
