Hazard Communication

Introduction

We encounter chemicals almost every day Filling your vehicle with gasoline Cleaning the bathroom Using various chemicals at work Applying pesticides or insecticides

Many chemicals can cause injury or illness if not handled properly

“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

Dihydrogen Monoxide

Health Effects Can cause excessive sweating and vomiting Can cause severe burns in gaseous form Found in tumors of terminal cancer patients Accidental inhalation can cause death

Environmental Effects Contributes to erosion Decreases effectiveness of automobile

brakes Major component of acid rain
