Liquid/gas under pressure
: skin penetration resulting in injuries, poisoning, eye damage. Fluids or gasses
under pressure can cause severe skin or eye damage due to their impact when flowing through fine openings.
They can even enter the body, resulting in poisoning. Before taking any action, check out the situation.
Eventually put pieces of cloth around the parts that need to be opened so that possible fluids or gasses get
diffused. Close off isolated areas, so the fluids can be drained away and the pressure removed.
Heavy or loose parts
: injuries by mechanical impact from twisting or carrying heavy weights. Use pulleys
and gloves when assembling heavy parts. Save your strength. Use tools such as crowbars and hydraulic
pumps as lever or power intensifier. Appoint a coordinator when several persons are working on the same
job. Watch out for injuries from crushing during assembly work.
Vacuum created by steam and/or hot water cooling down
: injuries by under pressure. A vacuum can be
created in machine parts that are closed off from the atmosphere and are cooling down, after they were filled
with steam and/or hot water. By opening these areas, severe suction can be created by under pressure. Make
sure not to expose body parts to these openings, since this could cause skin injury.
Water-hammer
. A mixture of 2 media such as water and steam in 1 pipe can create a water-hammer. This
is a ball of water blocking an entire section of the pipe. It moves forward via the steam against the steam
speed. At seams or curves in the pipes, this ball of water can create an impact or become a water-hammer.
Seams can be torn so that the steam escapes and/or the fixing of the piping gets damaged.
Pre-stressed springs
: injuries by mechanical impact. Loosening parts with pre-stressed springs can cause
injuries by a sudden position change of the parts. Check out how these parts are interlinked first. Use
accessories such as pins to disassemble parts with pre-stressed springs.
Parts not strong enough to support heavy weights
: Some parts can bend or break with overloads. Parts can
never be used as a platform, support or connector. Use ladders or platforms.
Electrical parts
: electrocution. Always cut the electrical power when working on electrical components.
This can be done by locking the main switch or by removing its key, when there is one available. Should
repair or maintenance be needed when the equipment is under current, use rubber gloves, isolated tools and
isolation between the body and the earth.
Chemicals :
burns and/or poisoning. Wear face mask, chemical gloves and protective clothing when
manipulating chemicals. Keep the technical data on all chemicals used available for persons working with
them. Make sure to note down the phone number of the poison control centre and local aid services.
Noise hindrance
: deafness, communication problems. Wear ear protection. If you work with 2 or more
persons in a noisy environment, make sure to communicate clearly. Eventually leave the noisy area to make
sure communication is not misinterpreted.
Human error :
bad maintenance or wrong interpretation of circumstances. Provide training to operators and
maintenance workers.
Automation
: unexpected circumstances f.i. automatic start of installation. A steam generator and its parts
can cause all of the safety hazards explained above, during maintenance or inspection. Although the
equipment is well protected, caution is needed at all times. Only trained personnel can operate or maintain
the generator, its devices or parts.
Please find below an explanation of the specific safety hazards, per part :
2.4.2
PUMP
Hot surface
: The pump (1 or 2 depending on the model) is fed with hot water from the hotwell.
Frost :
Do maintenance if a generator is not used during cold periods, ice can be formed in the parts
containing water
