Information about the residual risks |
43
L.1.7.3
Risk of rotating impeller caused by stack effect (chimney effect).
Hazards/dangerous area:
• On special occasions stack effect – also called chimney effect – in the ducts create airflows that drives the impellers
by turned off motors.
Dangerous incident:
• Injury of fingers, hands and arms.
Claim for reduction of danger:
• Eliminate this airflow for supply air and exhaust air by dampers with spring return motors for automatic closing of
the dampers by turned off fan motors and by power failure.
L.1.8
Batteries for heating
L.1.8.1
Extreme temperatures - heating
Hazards/dangerous area:
• Electrical heating elements can achieve surface temperature of 500 degree Celsius.
• Batteries and pipes for hot water can achieve 95 degree Celsius.
Dangerous incident:
• According to ISO 13732-1:2006, here is no direct risk of burns. (short-time contact – lesser than 2,5 sec).
Claim for reduction of danger:
• No.
L.1.8.2
Extreme temperatures - cooling
Hazards/dangerous area:
• Evaporator coil and pipes connected to cooling compressor can achieve minus 10 degrees Celsius.
Dangerous incident:
• According to ISO 13732-1:2006, here is no direct risk of injury. (short-time contact – lesser than 2,5 sec).
Claim for reduction of danger:
• No.
L.1.9
Heat pump units
L.1.9.1
Risk of high temperature
Hazards/dangerous area:
• Condenser coil and pipes can achieve temperature of 60 degree Celsius.
Dangerous incident:
• According to ISO 13732-1:2006, here is no risk of burns. (short-time contact 2,5 sec).
Claim for reduction of danger:
• No
L.1.9.2
Risk caused by lightning strike
Hazards/dangerous area:
• Lightning strike close to the machine.
Dangerous incident:
• Lightning strike can create flash over between phases and conductive parts. This can cause fire or the overvoltage
can make injury on persons
