Chemical Hazard Symbols

Type Labels

Function

Corrosive

-This symbol designated substances which may explode under definite conditions.

- Spontaneously flammable substances - Highly flammable gases Flammable - Substances sensitive to moisture - Flammable liquids

Oxidising

- Oxiding substances can ignite combustible material or worsen existing fires and thus makes fire fighting more difficult.

Harmful

- When taken up by the body, these substances cause slight damage.

Toxic

- The substance are very hazardous to health when breathed, swallowed or in contact with the skin and may even lead to death.

Questions : 1. According to the dress code, what should you wear in the laboratory? - Lab coat - Eye protection - Gloves - Hearing protection - Respirator 2. What type of goggles should you wear and when should you wear them? - Safety goggles, to protect the area surrounding eyes in order to prevent particulates, water and chemicals from striking eyes. 3. In what cases might you be asked to leave the laboratory? - When I dressed inappropriately such as wearing contact lenses, uncovered shoes and do not wear lab coat. - When a large amount of hazardous substances spilled and can risk others health and safety. - Upon hearing the fire alarm without assuming that the alarm is false or the system is being tested. 4. Can you wear contact lenses? Why? - No, I cannot wear contact lenses in laboratory because vapors and toxic fumes may get trapped beneath the contact lenses and harmed my eyes. 5.

What should you do if:

a) You broke a beaker and cut your finger - Use broom and dustpan to clean the broken glass and disposed it in a broken glass container. Next, Rinse my finger and check for broken glass. If bleeding is extensive, I should apply pressure to the wound. b) Chemicals have splashed on your face. - Go to eyewash immediately and wash my face with running water for at least 15 minutes c) The fire alarm sounds. - Exit the laboratory immediately using the exit door. d) Your shirt has caught on fire. - Do not run because the air will increase the flames. Drop to the floor and roll or use wool fire blanket to smoother the flame and keep it away from neck and face.

e) Chemicals have spilled on your pants. - For small chemicals, rinse with large amount of water for at least 15 minutes. For large chemicals, go to the safety shower immediately, remove clothes and shower for at least 15 minutes. References : 1) General Lab Safety Rules and Procedures. (n.d).
