In getting ready for work in hot environments, consider these points according to the American Industrial Hygiene Association's suggestions:
- Ensure there are enough refreshing drinks available.
- Identify the main source of heat stress and figure out ways to reduce it, especially concerning strategies for protective clothing.
- Assess if radiant shielding, including shade, is strategically positioned.
- Check if temperature monitoring equipment is on hand at the work site.
- Provide workers and supervisors with suitable work guidelines for the situation.
- Ensure appropriate first aid supplies are accessible for heat/cold emergencies.
- Determine an appropriate work rate, ensuring there is enough manpower to meet schedules despite a potentially slower pace.
- Instruct supervisors to promptly remove workers at the first sign of any issues.
- Confirm that workers have undergone proper acclimatization (or reacclimatization after a break from the challenging environment).
- Set up a cool recovery/rest area.
- Train workers and supervisors to recognize symptoms and administer first aid for heat injuries.
- Establish a reliable means of calling emergency medical support, making sure workers know how and where to contact them.
- Evaluate if clothing is suitable, allowing for minimal hindrance to sweat evaporation and maximal protection from radiant heat. Opt for the lightest, most permeable clothing that ensures safety.
- Maximize air velocity where practical.
- Confirm workers are well-hydrated at the beginning of their shifts.
- Assess the availability of spot cooling.
- Provide microclimate cooling options, such as cool vests, as needed.
- Remind workers of appropriate safety precautions.
- Safeguard workers who are pregnant, have relevant medical conditions, take medications that increase their risk, experienced prior heat injuries, or currently have a fever from elevated internal body temperatures.
