Cold weather workwear advice

OnSite Support provide some top tips on essential PPE for staying dry and warm this winter 

AS outdoor workers brace themselves for snow and heavy weather conditions in January, employers should ensure that they have personal protective clothing (PPE) that keeps them safe, warm and protected from the elements.

‘Snow, wet and cold weather conditions increase workplace accidents and illness at this time of year, so it’s important to minimize these risks by making sure your employees are visible, warm and properly dressed for the outdoor weather conditions,’ said OnSite Support safety workwear specialist Chris Wellgreen.

He offers the following advice on essential PPE winter workwear for staying warm and dry during the cold months ahead:

Keeping warm: The body loses up to 30 times more heat in cold wet weather and about 10% of this is lost through the head. It is also the wind chill that can make people feel colder and cause as much as 80% of total body heat loss.

Winter work coats and trousers should be durable, breathable and provide thermal and waterproof protection. It is important, too, that they are lightweight and comfortable so that they do not restrict movement and are easy to put on and take off.

Hooded jackets and coats, which keep the head and body warm and dry, and offer multiple layers of insulation which can be added or removed to suit outdoor conditions, are a cost-effective clothing solution.

Staying dry: PPE waterproofing levels can vary from very basic rain-protection workwear to high-performance heavy-weather gear, based on water penetration resistance that is measured in millimetres.

For very wet conditions involving lengthy periods of exposure, hi-vis clothing that offers a water penetration resistance to EN343:2003 Class 3:3 standard is recommended.

Being seen: There are three classes of hi-vis garments based on their levels of visibility. BS EN471 Class 3 is the highest grade and most visible clothing.

Hi-vis clothing must be clean and reflect from all angles, and be visible during the day and at night. It also needs to fit properly and meet ISO EN 20471:2013 for high-visibility warning clothing – a European standard, recognized by a ‘CE’ mark. The standard gives safety specifications for coveralls, jackets, waistcoats and trousers.

Hand protection: If working in temperatures below 4°C, gloves that offer thermal and water-resistant protection, as well as good grip and flexibility, should be worn. Good options include insulated gloves with a coating of nitrile material. 

Grip and traction: Safety footwear should provide warmth, waterproofing, traction and grip to prevent slips and falls on site. The Health and Safety Executive recommends grooved non-slip rubber or neoprene soles. The thermal lining should be waterproof to keep the feet warm while allowing them to breathe to prevent overheating.
