Question

snc2p chemistry unit name: * the ghs system also defines an environmental hazards group this group (and its classes) was not adopted in whmis 2015. however, you may see the environmental class(es) listed on labels and safety data sheets (sdss) including information about environmental hazards is allowed by whmis 2015 2. match the correct answer from column a with column b. a. compressed gas 1. can cause eye and skin irritation or eat through materials. b. biohazardous infectious material 2. may cause death if ingested c. flammable and combustible material 3. may burst into flames when exposed to a spark. d. corrosive material 4. may explode if heated or damaged e. oxidizing material 5. may cause unexpected reactions f. poisonous and infectious causing immediate toxic effects. 6. may contain harmful micro - organisms g. poisonous and infectious causing other toxic effects 7. may cause serious long term health problems in a person repeatedly exposed. h. dangerously reactive materials 8. may react violently if in contact with combustible material.

Explanation:

To solve the matching problem, we analyze each term in Column A and match it with the correct description in Column B:

• a. Compressed gas: Compressed gases (like those in gas cylinders) may explode if heated or damaged (matches 4).
• b. Biohazardous infectious material: These contain harmful microorganisms (matches 6).
• c. Flammable and combustible material: Such materials may burst into flames when exposed to a spark (matches 3).
• d. Corrosive material: Corrosive substances can cause eye/skin irritation or eat through materials (matches 1).
• e. Oxidizing material: Oxidizers may react violently with combustible materials (matches 8).
• f. Poisonous and infectious (immediate toxic effects): Immediate toxic effects can cause death if ingested (matches 2).
• g. Poisonous and infectious (other toxic effects): Long - term exposure to these causes serious health problems (matches 7).
• h. Dangerously reactive materials: These may cause unexpected reactions (matches 5).

Answer:

a. Compressed gas - 4
b. Biohazardous infectious material - 6
c. Flammable and combustible material - 3
d. Corrosive material - 1
e. Oxidizing material - 8
f. Poisonous and infectious causing immediate toxic effects - 2
g. Poisonous and infectious causing other toxic effects - 7
h. Dangerously reactive materials - 5
