Summer is here, and "Heat Stress" is a danger to workers in summer. What are your suggestions to have no incident this summer?

Hi there According to (The National Institute for Occupational Safety and Health (NIOSH), follwoing best practices steps may help you protect your labours and workers from heat stress: You can start by providing heat stress training or awareness sessions to all labours and workers, the training should incldue the following information: - Worker risk - Prevention - Symptoms - The importance of monitoring yourself and coworkers for symptoms - Treatment - Personal protective equipment Also employers thshould condier the follwoing steps to protect their workers from heat stress: - Schedule maintenance and repair jobs in hot areas for cooler months.
- Schedule hot jobs for the cooler part of the day.
- Acclimatize workers by exposing them for progressively longer periods to hot work environments.
- Reduce the physical demands of workers.
- Use relief workers or assign extra workers for physically demanding jobs.
- Provide cool water or liquids to workers.
- Avoid alcohol, and drinks with large amounts of caffeine or sugar.
- Provide rest periods with water breaks.
- Provide cool areas for use during break periods.
- Monitor workers who are at risk of heat stress.
Workers should avoid exposure to extreme heat, sun exposure, and high humidity when possible.
When these exposures cannot be avoided, workers should take the following steps to prevent heat stress: - Wear light-colored, loose-fitting, breathable clothing such as cotton.
- Avoid non-breathing synthetic clothing.
- Gradually build up to heavy work.
- Schedule heavy work during the coolest parts of day.
- Take more breaks in extreme heat and humidity.
- Take breaks in the shade or a cool area when possible.
- Drink water frequently.
Drink enough water that you never become thirsty, Approximately 1 cup every 15-20 minutes.
- Avoid alcohol, and drinks with large amounts of caffeine or sugar.
- Be aware that protective clothing or personal protective equipment may increase the risk of heat stress.
- Monitor your physical condition and that of your coworkers.
Hope above is useful and help you to ensure zero incident during the summer.
Regards,

the ministry of labor is going to announce the timing for working in summer, and they also conducting trainings for heat stress.
you are really a professional Mr.
Ruhul for pointing out such issues in good times.

How does the body react to heat? The body reacts to heat by increasing the blood flow to the skin’s surface, and by sweating.
This results in cooling as sweat evaporates from the body’s surface and heat is carried to the surface of the body from within by the increased blood flow.
Heat can also be lost by radiation and convection from the body’s surface.
Typical example of a heat stress situation Someone wearing protective clothing and performing heavy work in hot and humid conditions could be at risk of heat stress because: Sweat evaporation is restricted by the type of clothing and the humidity of the environment.
Heat will be produced within the body due to the work rate and, if insufficient heat is lost, deep body temperature will rise.
As deep body temperature rises the body reacts by increasing the amount of sweat produced,which may lead to dehydration.
Heart rate also increases which puts additional strain on the body.
If the body is gaining more heat than it can lose the deep body temperature will continue to rise.
Eventually it reaches a point when the body’s control mechanism itself starts to fail.

one of my colleague attended a recent workshop from UAE government regarding heat stress and we are currently making safety for this hazard.

An ounce of salt, a gallon of water and a hat on your head!

 Reduce the physical demands of workers. - Use relief workers or assign extra workers for physically demanding jobs. - Provide cool water or liquids to workers. - Avoid alcohol, and drinks with large amounts of caffeine or sugar. - Provide rest periods with water breaks. - Provide cool areas for use during break periods. - Monitor workers who are at risk of heat stress.

Hope above is useful and help you to ensure zero incident during the summer. Regards,

conducting safety tool awareness before start of work specially in hot season will guide everyone in their daily activities.

During a Construction Project for a factory , especially during Ramadan when heat is at its peak, I did allow complete freedom to local engineers not to miss their social interactions but in discussion with expat workers and staff, observed work during evening and thru night with special food packets organised for their eating during night and at stoppage of work so that they can observe the religious duties without any obstruction.I could achieve more than 80% work efficiency during Ramadan.For normal working days during Summer, strict observance of rest period as per dictat from Ministry of labour was observed and special spaces for rest by workers were also organised. Emergency response kit and ambulance to take care if any heat stroke emergency arises were also oin place.

Engineering controls: Insulating or shielding hot surfaces to reduce radiant heat,  providing air conditioning or ventilation to remove hot air or reduce humidity, eliminating heavy work or having it done at a time or place where the heat hazard will not exist.

Administrative controls: Acclimatize workers to the heat, supervise work, provide water and encourage workers to drink it, salt tablets are not recommended because they take a long time to enter the system, there are recommendations for work rest cycles in different conditions and types of heat, plan to adjust work/rest schedules according to broadcast humidex or temperature ratings, if personal protective equipment is required, ensure any heat retention caused by it is taken into consideration when planning the work.

Personal protections: Schedule work to be done in the shade or cool times of the day where possible, wear loose fitting, tightly woven clothing that covers arms and legs, sunscreen of at least a SPF should be used on all exposed skin, those working outside should have good sunglasses that filter out UVA and UVB wavelengths, wear a hat with a tight weave and a three inch brim all around.
