Keep your greenhouse safe during a heatwave

By taking preventive measures, you can reduce the risk of breakdowns, damage, and unsafe situations. The tips below can help you keep your greenhouse business safe and under control during hot weather.

1. Protect your employees from the heat

Hot weather can have a major impact on employees. Consider the following measures:

• Adjust working hours where possible, for example by starting earlier.
• Wear light, breathable clothing and use a cap or other head protection when needed.
• Protect employees from the sun, both outside and inside the greenhouse. Use sunscreen (SPF 20 or higher) and reapply regularly.
• Consider cooling vests or cooling caps for extra comfort.
• Use a summer schedule: start early and finish earlier on very hot days.
• Plan heavy or physically demanding tasks in the morning.
• Adapt work schedules to the weather forecast.
• Provide shade and ventilation where possible.
• Switch off heat-producing equipment temporarily if possible.
• Encourage employees to look after themselves and each other during periods of high temperatures.

2. Pay extra attention to empty greenhouses and buildings

Temperatures can rise very quickly in unused areas. To prevent excessive heat:

• Ensure good ventilation by opening windows, vents, and doors. Make sure they are closed again in time if weather conditions change, such as during thunderstorms.
• Increase humidity by spraying water for natural cooling.
• Avoid empty PVC pipes. Flush PVC pipes regularly by using water sprays. This helps cool both the room and the pipes.
• Close screens to reduce direct sunlight and heat build-up.

3. Check rooms with technical equipment

Heat can build up quickly in technical and utility rooms.

• Check for hot spots near electrical panels.
• Open doors to improve air circulation.
• Install extra fans where possible.

4. Monitor your water supply

Water systems are especially vulnerable during hot weather.

• Check more frequently for blockages, for example caused by algae growth.
• Inspect your water storage regularly for both quantity and quality, including signs of algae growth, and take action if needed.

5. Check your cold storage room

A properly functioning cold storage room is essential.

• Make sure the cold room is maintaining the correct temperature.
• Inspect and clean cooling compressors and carry out necessary maintenance.

6. Keep inspecting your site

• Carry out regular inspection rounds across your business.
• Do not rely on monitoring data alone.
