Health and safety in manufacturing machinery operation
Health and safety in New Zealand’s manufacturing sector starts with the operation of machinery. Under the Health and Safety at Work Act 2015, businesses must ensure all equipment is used safely to prevent crushing, shearing, or entanglement injuries.
Effective machinery maintenance and safety involve:
- Guarding: Ensuring all moving parts have secure, functional guards that cannot be easily bypassed.
- Lockout/Tagout: Implementing strict procedures for isolating power during maintenance or cleaning.
- Training: Providing comprehensive supervision and training for all machine operators.
- Emergency Stops: Verifying that all emergency stop mechanisms are accessible and functional.
Review: Are you tracking the maintenance of your machinery and have you got the correct standard operating procedures in place for your teams to follow?
Managing Hazardous Substances and Toxic Exposures
Managing environmental health and safety in manufacturing requires strict controls over hazardous substances. WorkSafe's current assessment places significant weight on how businesses protect workers from chronic illness caused by long-term exposure to airborne contaminants.
Key risks identified include:
- Toxic Dust Exposure: Specifically wood dust and silica dust, which require local exhaust ventilation (LEV).
- Fumes Exposure: Managing welding fumes and chemical vapours through proper extraction and PPE.
- Chemical Exposure: Ensuring correct storage, handling, and use of industrial solvents and treatments.
- Inventory Management: Keeping an up-to-date hazardous substances register and safety data sheets (SDS).
Review: Are your teams handling hazardous substances correctly and do they know how to update the hazardous substance register and safety data sheets?
Understanding Upstream Duties for Manufacturers
Under HSWA, upstream duties apply to those who design, manufacture, import, or supply plant and substances. These duty holders must ensure their products are "safe by design" before they even reach the end-user's factory floor.
"Upstream businesses are in a strong position to eliminate or minimise risk at the source, rather than relying on downstream users to manage hazards through PPE or administrative controls." - WorkSafe NZ.
Manufacturers must:
- Carry out testing to ensure products are without health and safety risks.
- Provide adequate information on the intended use and results of safety tests.
- Consider the lifecycle of the product, including maintenance and decommissioning
