Growsafe Personal Protective Equipment — Questions and Answers
Question 1: According to NZ Growsafe standards, what is the minimum PPE required when handling concentrate agrichemicals?
- Chemical-resistant gloves, overalls, eye protection, and appropriate respirator (Correct answer)
- Standard work gloves and gumboots
- A dust mask and long sleeves
- High-visibility vest and safety glasses
Correct answer: Chemical-resistant gloves, overalls, eye protection, and appropriate respirator
When handling concentrate agrichemicals in NZ, the minimum PPE includes chemical-resistant gloves, coveralls or overalls, eye protection (goggles or face shield), and an appropriate respirator as specified on the product label.
Question 2: What type of respirator filter is typically required when spraying organophosphate insecticides in New Zealand?
- A2 organic vapour filter combined with P2 particulate filter (Correct answer)
- P1 dust filter only
- Standard surgical mask
- SCBA (Self-Contained Breathing Apparatus)
Correct answer: A2 organic vapour filter combined with P2 particulate filter
Organophosphate insecticides typically require an A2 organic vapour filter combined with a P2 particulate filter to protect against both vapour and mist/aerosol exposure during spraying.
Question 3: How often should chemical-resistant gloves be checked for integrity according to NZ Growsafe guidelines?
- Before every use (Correct answer)
- Once a month
- Only when visibly damaged
- At the annual Growsafe recertification
Correct answer: Before every use
Chemical-resistant gloves should be inspected before every use by inflating them and checking for leaks, cracks, or degradation that could allow chemical penetration.
Question 4: In NZ, where should you find the specific PPE requirements for a particular agrichemical product?
- On the product label and Safety Data Sheet (SDS) (Correct answer)
- In the Growsafe handbook only
- On the EPA website only
- From the chemical sales representative
Correct answer: On the product label and Safety Data Sheet (SDS)
The product label and Safety Data Sheet (SDS) are the primary and legally binding sources for PPE requirements specific to each agrichemical product in New Zealand.
Question 5: What is the correct order for removing contaminated PPE after agrichemical application?
- Gloves last — remove outwear first while gloves protect your hands (Correct answer)
- Gloves first, then everything else
- Remove respirator first, then gloves
- Order does not matter as long as you shower after
Correct answer: Gloves last — remove outwear first while gloves protect your hands
Gloves should be removed last because they protect your hands from contamination while you remove other items of PPE. Removing gloves first would expose your hands to contaminated surfaces.
Question 6: According to NZ standards, what should be done with PPE that has been heavily contaminated during an agrichemical spill?
- Decontaminated if possible, or disposed of as hazardous waste (Correct answer)
- Washed with standard laundry detergent
- Stored separately for the next spill response
- Returned to the chemical supplier for cleaning
Correct answer: Decontaminated if possible, or disposed of as hazardous waste
Heavily contaminated PPE should be decontaminated following proper procedures if possible, or otherwise disposed of as hazardous waste through an approved facility — not simply washed with standard detergent.
