Ali is using a metal cleaning product

and pours some into an empty water

bottle. Later, he accidentally picks up

the wrong bottle and drinks the toxic

chemical. Ali dies from intoxication.You must always clearly identify

hazardous material containers and

use them only for that purpose.

Hazardous Materials

The high number of times hazardous chemicals are handled on

construction sites increases the risk of an accident. Chemicals

can also interact and become even more dangerous for workers.

Introduction

Hazardous Materials

Hazardous materials contain chemicals that can injure or affect

the health of workers. For example:

Cleaning or stripping products;

Chemicals; Explosives;

Hazardous gasses.

that can catch fire easily. Workers must:

Keep them away from any source of flame;

Store them in a cabinet protected by a firewall

(hazardous materials storage locker).

themselves. Oxidizers can create a fire with a

flammable material even in the absence of air.

Workers must:

Keep them away from combustibles and flammablematerials.

Toxic materials (poisons) are products that cause

immediate and serious toxic effects. Workers must:

Avoid any direct contact with them;

Wear the required PPE appropriate for the situation

before handling them;

Work in a well-ventilated space.
