Health Hazards Routes of entry Toxicity Dose-response Permissible Exposure Limits Effects on the body

Routes of Entry Inhalation Absorption Ingestion

Toxicity Ability of a substance to produce an unwanted effect Commonly compares one chemical agent with another Median lethal dose Oral LD 50 Skin LD 50 Inhalation LC 50

Toxicity AgentLD 50 (mg/kg) Ethyl Alcohol10,000 Sodium Chloride4,000 Caffeine200 Nicotine1 Dioxin0.001 Botulinum toxin

Dose - Response Degree of toxicity Amount of exposure Length of exposure time Personal sensitivity Combined chemical exposures

Permissible Exposure Limits CCR 8, § 5155 Approximately 700 substances Permissible Exposure Limits (PEL) Short Term Exposure Limits (STEL) Ceiling limits (C) Skin notation (S)

Health Effects Carcinogens Toxic or highly toxic agents Reproductive toxins Irritants Corrosives Sensitizers Target organ effects

Health Effects Acute Occur rapidly after short-term exposure Short duration Chronic Long-term exposure Long duration

Labeling General requirements Manufacturer’s labels Secondary labels

General Requirements The product name A warning statement, message, or symbol On commercial labels, manufacturers of hazardous materials must include their name and address. Many manufacturers also include a statement describing safe handling procedures.

Manufacturer Label

Signal Words Danger Imminently hazardous situation, death or serious injury Warning Extra warning to save lives, reduce injury, assist emergency personnel Caution Warn against potential hazards or to caution against unsafe practices

Material Safety Data Sheets Definition Description American National Standards Institute ANSI standard Z Hazardous Industrial Chemicals – Material Safety Data Sheets - Preparation Department of Labor Form 174

Material Safety Data Sheet Written or printed material concerning a hazardous substance prepared to meet the requirements of the Hazard Communication Regulation Also called MSDS

MSDS Description Contains detailed information on a chemical and its hazards Additional information not on a label Required for each chemical at the District Different from manufacturer to manufacturer

ANSI Format Contains all information required on OSHA Form 174 Additional useful information Arranged in a consistent format More likely to be consistent from country to country 16 sections

“Right To Know” District Rights: Material Safety Data Sheets (MSDS) provided by manufacturer or distributor Responsibilities: Written Program Training and MSDS available to employees Employees Rights: Access to information Responsibilities: Work safely with chemicals

Summary Chemicals can be used safely Plan before chemicals are used Check labels and read the MSDS Ask if unsure about a chemical Think about coworkers and students
