25 May Common Winter Workplace Hazards (And How To Manage Them)
As winter sets in across New Zealand, businesses face a new range of seasonal workplace hazards that can significantly impact worker safety, productivity, and compliance.
From slippery surfaces and freezing mornings to poor visibility on the roads, winter conditions can increase the likelihood of incidents if businesses are not prepared.
For small businesses, construction sites, farms, warehouses, and transport operators, understanding and proactively managing winter-related hazards is essential.
1. Slips, trips, and falls
Winter weather often creates wet, muddy, frosty, or icy conditions that increase the risk of slips, trips, and falls.
Common winter slip hazards include:
- Frost-covered footpaths or stairs;
- Rain-soaked entrances;
- Muddy farm or construction sites;
- Wet warehouse floors; and
- Poor drainage in outdoor work areas.
These incidents can lead to sprains, fractures, lost productivity, and even serious injuries.
How to reduce the risk:
- Install anti-slip mats at entrances;
- Grit or salt icy walkways;
- Improve drainage systems;
- Ensure prompt spill clean-up;
- Provide slip-resistant footwear; and
- Increase winter housekeeping inspections.
Tip: Review your hazard register before winter begins and update controls for seasonal risks.
2. Cold stress and worker exposure
Cold temperatures, rain, and wind chill can impact workers’ physical health and mental alertness.
This is particularly relevant for:
- Construction workers;
- Agricultural and horticultural teams;
- Delivery drivers;
- Outdoor maintenance crews; and
- Staff working in refrigerated or poorly heated environments.
Risks of cold exposure:
- Reduced dexterity;
- Fatigue;
- Poor decision-making;
- Hypothermia; and
- Increased accident likelihood.
Practical controls include:
- Warm waterproof PPE;
- Scheduled warm-up breaks;
- Access to heated break areas;
- Weather monitoring systems;
- Task rotation for outdoor staff; and
- Clear cold-weather work procedures.
Protecting workers from cold stress is not just about comfort – it directly supports safety performance.
3. Winter driving and reduced visibility hazards
Shorter daylight hours, fog, heavy rain, and black ice can significantly increase vehicle and machinery risks.
Common winter transport hazards:
- Rural road black ice;
- Fog reducing visibility;
- Flooded roads;
- Poorly lit worksites; and
- Vehicle braking issues on wet roads.
For businesses with fleet vehicles, delivery teams, or mobile workers, winter driving safety is critical.
Risk reduction strategies:
- Conduct regular vehicle maintenance checks;
- Train workers in winter driving safety;
- Ensure headlights and tyres are roadworthy;
- Adjust schedules to avoid hazardous travel conditions;
- Improve site lighting; and
- Review journey management plans.
Vehicle incidents can become one of the highest seasonal business risks during winter.
Preparing your business for winter safety
Winter is an ideal time to review your overall health and safety systems.
Key documents to review:
- Hazard registers;
- Safe Operating Procedures (SOPs);
- PPE requirements;
- Vehicle safety policies;
- Emergency response plans; and
- Incident reporting systems.
By identifying winter-specific hazards early, businesses can reduce injuries, improve worker confidence, and maintain compliance with New Zealand health and safety obligations.
