Hazard Communication
The Problem
Chemical hazards are present in many New Zealand workplaces, but the biggest risk is not understanding or knowing how to handle these substances safely. Without proper hazard communication, workers may encounter unlabelled containers, missing or incomplete Safety Data Sheets (SDS), or poorly stored chemicals—leading to accidents, injuries, or long-term health issues. Today, we’ll discuss how New Zealand’s Hazardous Substances regulations ensure your right to know about the hazards around you and how to protect yourself.
Identify the Hazards
- Unlabelled or Incorrectly Labelled Chemicals: Increases the chance of accidental misuse.
- Incomplete or Inaccessible SDS: Prevents workers from understanding chemical properties and safety precautions.
- Improper Storage: Can lead to dangerous chemical reactions, leaks, or the build-up of hazardous vapours.
- Inadequate Emergency Preparedness: Delayed response to chemical spills or exposures can worsen injuries.
Safety Practices and Preventative Measures
Chemical Identification and Labelling:
- Maintain an up-to-date register of all hazardous substances onsite.
- Ensure all containers are clearly labelled with:
- Product name
- Hazard pictograms and classification under the GHS (Globally Harmonised System)
- Signal words (e.g., Danger, Warning)
- Precautionary statements
- Product name
- Label secondary containers clearly with the product name and hazard classification.
Access and Use of Safety Data Sheets (SDS):
- SDS must be readily accessible to all workers during their shifts, either physically or electronically.
- Learn how to read key SDS sections, including:
- Hazard identification
- First aid measures
- Safe handling and storage
- Hazard identification
- Report any missing or outdated SDS to your supervisor.
Chemical Storage Requirements:
- Store substances based on compatibility—never mix incompatible chemicals.
- Use secondary containment for liquids to prevent environmental harm.
- Ensure proper ventilation in storage areas to reduce vapour build-up.
- Use flammable goods cabinets for storing flammable liquids.
- Regularly inspect storage areas for compliance with the Health and Safety at Work (Hazardous Substances) Regulations 2017.
Emergency Procedures and Equipment:
- Make sure emergency eye wash and safety showers are accessible within 10 seconds of hazardous work areas.
- Keep spill kits available, stocked, and ready for immediate use.
- Follow the site’s emergency procedures for spills or exposures.
- Display emergency contact details and first aid information clearly.
Real-Life Case or Scenario
Consider this real example: A worker used an unlabelled bottle they believed was a regular cleaning solution. It turned out to contain a caustic substance, resulting in chemical burns. The container had no label and there was no SDS available. This incident could have been prevented with proper labelling and accessible hazard information.
Employee Responsibilities
- Always check for labels and hazard symbols before using any chemical.
- Report missing labels, unmarked containers, or inaccessible SDS immediately.
- Use all required PPE when handling hazardous substances.
- Complete hazardous substances training and apply it consistently.
Employer Responsibilities
- Maintain an accurate hazardous substances inventory and ensure correct labelling.
- Provide SDS and ensure they are accessible to all staff.
- Train workers in chemical safety and handling procedures.
- Maintain compliant chemical storage areas and respond quickly to reported hazards.
Discussion & Questions
- "Have you ever encountered an unlabelled chemical container or missing SDS onsite?"
- "Do you feel confident in understanding SDS information?"
- "Are there any specific chemicals onsite that we should review procedures for?"
Encourage open discussion and feedback from the team.
Commitment/Action Plan
Let’s commit to identifying and understanding chemical hazards by ensuring every chemical is labelled correctly and supported by an accessible SDS. If something is unclear or unlabelled—stop and report it. Safety begins with knowledge.
Wrap-Up
Hazard communication is essential for safety. By staying informed and following the correct procedures, we protect ourselves, our team, and our workplace. If you’re unsure about any chemical or label—speak up, check the SDS, and ask for help.
Standards Overview
WorkSafe New Zealand requires:
- A hazardous substances inventory for each workplace.
- All containers to be correctly labelled in accordance with GHS.
- SDS for each hazardous substance to be available to all workers.
- Safe storage and emergency response procedures.
These rules are set out in the Health and Safety at Work (Hazardous Substances) Regulations 2017.
