Is it harmful for the furnace foreman to work by the fire at 170℃ every year? Contact with fire is only 2 minutes at a time.

Hypertension is a common occupational disease of boiler workers. I used to work in a furnace. Pay more attention to drinking water at ordinary times, but don't mix it with too cold, otherwise it will be bad for internal organs. If I don't feel well, I must rest in time. Once heatstroke occurs, it can't be found in time. The consequences are very serious. As for low back pain, it must be long-term coal fatigue. Do more massage during rest to prevent muscle adhesion from causing other waist diseases. It's best to do some exercise when you are free, which will help your body return to normal.
