HAZARD AND RISKS

You are working in a chemical lab, and a spill has occurred. Some of the containers near the spill have hazard symbols on them. You need to react quickly to avoid a serious accident. Answer the following questions to mitigate risks and ensure everyone's safety. You notice a bottle labeled with this symbol. What is the main risk associated with this substance?

• It is highly toxic if inhaled

• It can cause severe skin burns and eye damage

• It can cause long-term damage to the environment

• It can catch fire easily

The following situations occur in the lab. Choose the immediate action you would take for each:

A chemical with a toxic symbol spills on the floor

• Cover the spill with water

• Evacuate the area and alert the safety officer

• Continue working but avoid stepping in the spill

You come across a storage cabinet with the following hazard symbols, match the symbol with the correct risk

• Risk of combustion, especially when exposed to heat

• Risk of severe health effects if inhaled, ingested, or absorbed

• Risk of long-term damage to the environment, particularly aquatic life

In another section of the lab, you observe workers using a high-powered cutting machine without wearing gloves or protective goggles. Identify two hazards present in this situation

• Risk of electric shock from ungrounded tools

• Risk of fire from sparks created by cutting

• Risk of skin injury from sharp tools

• Risk of eye injury from flying debris

You hear a hissing noise coming from a gas cylinder labeled with a flammable gas symbo

• Turn off all ignition sources and evacuate the room

• Check the cylinder for cracks

• Open windows and continue working

What precautionary measures should be taken when handling this substance

• Store it away from water sources

• Wear respiratory protection to avoid inhalation

• Ensure the substance is kept away from other chemicals that can react with it

• Ensure it is stored in a cool, dry place, away from any heat sources or open flames

During maintenance work, a worker is using a ladder on uneven ground, and the ladder is not secured properly. Identify two hazards present in this situation

• Risk of back injury from improper lifting technique

• Risk of the ladder collapsing under load

• Risk of falling from height due to unstable ladder

• Risk of electric shock from working near power lines

A hazardous chemical spill with these labels has occurred in the lab. What should be your first response

• Contain the spill and alert lab personnel immediately

• Continue working but avoid the spill

• Open windows and try to ventilate the room

• Dilute the chemical with water

You are given the following hazard symbols: corrosive, oxidizing, and pressure. Classify the hazard symbol with the scenario. A chemical spills on the lab bench and begins eating through the surface.
