That is, if the activity time is equal to or less than the maximum time, the activity risk calculation unit 7 sets “no risk”, and if the activity time exceeds the excess time, the preset content is set as the activity risk.
- the activity risk calculation unit 7 may calculate the activity risk in consideration of the remaining amount of air in the air respirator possessed by the worker. In this case, the activity risk calculation unit 7 calculates the activity risk when the remaining amount of air is 50% or less, assuming that there is no margin in the remaining amount of air even if the activity time is the maximum time or less.
- the activity risk calculation unit 7 may calculate the activity risk according to the situation of the fire site, for example, the situation where there is a chemical substance at the site. In this case, the activity risk calculation unit 7 considers that even if the activity time is less than the maximum time, the risk increases when the on-site temperature approaches the ignition point or reaction temperature of the chemical substance, the melting temperature of the container, etc., and the activity risk Is calculated.
- the activity determination unit 8 determines whether or not the worker is performing normal activity from the activity degree estimated by the activity degree estimation unit 2 and the activity risk calculated by the activity risk calculation unit 7. For example, the activity estimation unit 2 estimates the activity of the worker's movement as "stationary” or "abnormal movement", and the activity risk calculation unit 7 determines the activity risk as "risk of heat stroke". When the activity determination unit 8 calculates, the activity determination unit 8 determines that the worker has collapsed and is not performing normal activity.
