HIGH PESSURE, HIGH VELOCITY HOT WATER IS DANGEROUS!
GENERAL PRESSURE CLEANER WARNINGS AND SAFETY PRECAUTIONS
• Caution – HOT WATER. Danger of severe burns. Proceed with caution!
• When shutting down, always turn off machine, turn off water at the source and trigger the
gun pointing the lance in a safe direction to release any in-line stored pressure - before
disconnecting hoses or working on machine.
• Never aim high pressure water jet at anyone, at animals or at fragile items - injury or
damage could result.
• Always be aware of overhead cables, run-off water, slippery surfaces and by-
standers!
• Never allow untrained adults or minors use of the equipment.
• Never use the machine if there are any leaks on the high pressure delivery side of the
pump.
• Read and observe the manufacturer's instructions if chemicals are being used.
• The “recoil” on larger machines is positive - lean forwards and brace yourself to take it up!!!
• NEVER HIGH PRESSURE BLAST THE FOLLOWING: any electrical components, motors
/ switchgear or electrical boxes as injury or death may result.
• Never water blast any fuel caps or oil caps and water can get into breather holes and
contaminate fuel or water. Never blast water directly into seals / bearings on shafts where
water penetration would be detrimental.
• NEVER WATER BLAST: fragile items / surfaces that may be damaged by high velocity
water. Always carefully test on a small area first.
• ALWAYS WEAR PROTECTIVE GEAR (PPE) i.e. Head, face, eye protection, wet weather
gear, boots and gloves - which is particularly important where hot water or aggressive
chemicals are being used or where whet sandblasting is used.
• Keep hands, feet and hair away from all moving parts.
• Never leave machine running unattended.
• EXTREME DANGER - never adjust engine speed (RPM) or safety by-pass valve in an
attempt to increase pressure!
• Barricade off immediate work area - restrict access - erect hazard warning signs.
• Never use high pressure water cleaner without protective canvas sheaths on operator end
of high pressure hose as a high pressure leak can injure operator.
• In commercial / industrial sites class 'b' units (pressures over 5,000 PSI) should have
additional operators allocated as safety observer / machine minder subject to work
conditions / environment. This is a responsibility of the 'site occupier' to determine.
• If two / three operators are working they should be physically separated by partitions /
barriers.
• Prior to high pressure water blasting, check location’s level of emergency /first aid.
• All machines are fitted with MEDIC ALERT tags. If a high pressure water injury occurs
which need medical attention, pull off machine and give it to the medical practitioner to read
