Growsafe Personal Protective Equipment 2 — Questions and Answers
Question 1: What does the term 'breakthrough time' mean regarding chemical-resistant gloves?
- The time it takes for a chemical to permeate through the glove material (Correct answer)
- The time it takes to put gloves on correctly
- The period a glove is rated to last before replacement
- The time required to decontaminate gloves after use
Correct answer: The time it takes for a chemical to permeate through the glove material
Breakthrough time is the measured time it takes for a specific chemical to permeate (pass through) the glove material. Different glove materials have different breakthrough times for different chemicals.
Question 2: In NZ, when should a half-face respirator be upgraded to a full-face respirator for agrichemical work?
- When the product label requires eye protection and respiratory protection simultaneously (Correct answer)
- Only when working in enclosed spaces
- When the temperature exceeds 25°C
- When the applicator has a beard
Correct answer: When the product label requires eye protection and respiratory protection simultaneously
A full-face respirator should be used when the product requires both eye and respiratory protection, as it provides an integrated solution covering both face and breathing zones.
Question 3: What material are NZ-approved chemical-resistant boots typically made from for agrichemical handling?
- PVC or nitrile rubber (Correct answer)
- Leather with waterproof coating
- Standard rubber gumboots
- Steel-capped work boots with canvas uppers
Correct answer: PVC or nitrile rubber
Chemical-resistant boots for agrichemical work are typically made from PVC or nitrile rubber, which resist chemical permeation. Standard leather or canvas boots can absorb chemicals.
Question 4: How should PPE be stored when not in use according to NZ Growsafe best practice?
- In a clean, dry area separate from agrichemical storage (Correct answer)
- In the same locked shed as the agrichemicals
- In the cab of the spray vehicle
- Hung on the outside of the chemical store for quick access
Correct answer: In a clean, dry area separate from agrichemical storage
PPE should be stored in a clean, dry, and well-ventilated area separate from agrichemical storage to prevent contamination and degradation of the protective equipment.
Question 5: What is the NZ standard for fit-testing of respirators used in agrichemical application?
- The respirator must seal properly to the face — fit testing ensures no leakage (Correct answer)
- Fit testing is optional if the respirator feels comfortable
- Any respirator that covers the nose and mouth is acceptable
- Only SCBA units require fit testing
Correct answer: The respirator must seal properly to the face — fit testing ensures no leakage
NZ standards require that respirators seal properly to the wearer's face. Fit testing ensures there is no leakage around the seal, which is critical because even small gaps can allow hazardous vapours or particles to be inhaled.
Question 6: Under NZ law, who is responsible for providing PPE to workers handling agrichemicals?
- The employer or PCBU (Person Conducting a Business or Undertaking) (Correct answer)
- The individual worker
- The Growsafe training organisation
- The agrichemical manufacturer
Correct answer: The employer or PCBU (Person Conducting a Business or Undertaking)
Under the Health and Safety at Work Act 2015, the employer or PCBU is legally required to provide appropriate PPE at no cost to workers who are exposed to hazardous substances.
