      Hazards and more Hazards
Serious injuries can occur in
car wash operations such as
electrocutions, chemical
burns, lacerations,
amputations, strains, struck-
by moving vehicles, and slips
and falls.

               High pressure
Working with high pressure washing equipment
or systems involves a variety of hazards
including contact with a high pressure waterjet,
uncontrolled hoses, and exposure to chemicals,
heat, cold, and noise. This equipment is
powerful enough to cause serious injuries
resulting in amputation or death. Even a minor
surface wound that doesn’t bleed may cause
severe internal tissue damage.

     Potential Chemical Hazards
• Certain pre-soak compounds used in
  automated equipment washes are very
  alkaline and corrosive and may be applied
  manually




                P bar Y Safety Consultants Alberta Canada
            CHEMICAL HAZARDS

Caution should be exercised in handling all chemical
products. Some car wash chemicals are caustic and
should not come in direct contact with bare skin or
eyes.
Read caution labels on any chemical products. Read
and understand the MSDS (Material Safety Data Sheet)
for each chemical product used. These sheets provide
important information regarding safe use, personal
protective equipment, storage and first aid.

Think Equipment/People/Environment
     when looking at the Hazards
When performing manual lifting tasks, obtain solid
footing. Stand close, bend your knees and keep your
back straight. Lift straight up, push with your legs.
Hold the load close to your body. Avoid twisting or
turning your body while lifting or carrying a load. Turn
feet to change body position.
If the object is too heavy for you, get someone to help
you. Use proper material handling aids such as hand
trucks, carts, etc.

     Potential Chemical Hazards
• Foaming agents for deep cleaning may be
  hazardous
• Coatings, rinses, waxes and polish water-
  resistant compounds may be quite alkaline or
  may cause dermatitis




                P bar Y Safety Consultants Alberta Canada
          Airborne Chemicals
• Mists from sprayed cleaning agents
• Emissions from diesel and gasoline engines
  – Composed of a complex mixture of thousands of
    different gases, vapors, and fine particles
  – Diesel engine emissions may contain potential
    cancer-causing substances such as arsenic,
    benzene, formaldehyde, nickel and polycyclic
    aromatic hydro-equipment bons


                P bar Y Safety Consultants Alberta Canada
Electrocution and Mechanical Hazards
Electrical Hazards
To reduce the possibility of severe injury or
death from electrical shock, employees should
not conduct any repairs unless they are qualified
and authorized by the company. Lockout/tagout
procedures should be followed when servicing
or maintaining equipment.


                P bar Y Safety Consultants Alberta Canada
            Exterior System
• High pressure water tank and pump that may
  feed all manual and automated spray
  machines; jets may operate up to 1000 PSI




               P bar Y Safety Consultants Alberta Canada
               Exterior System

                  Slips, Trips and Falls
• Accumulations of slippery soap, wax and other chemical solutions
   on floor areas
Good housekeeping is essential to a safe workplace
and may result in fewer accidents and reduced fire
hazards.
Remove tools, materials or other objects lying on
floors, driveways, and work areas. Clean up all spills
such as oil, detergent, wax, etc. Drain trenches must
be kept clean to minimize the amount of excess water
on the floor. Employees should wear slip-resistant
shoes. Employees should receive training in correct
ladder selection, inspection and safe use.

                 Struck-by Hazards

• Being struck by customer-driven or employee
  operated vehicles is a major hazard
• In all operations, a struck-by hazard exists either by
  vehicle or mechanical equipment
• Employees can be struck by a vehicle as it
  approaches or enters the bay, where it disengages
  from the conveyor system, where it is driven out, or
  where it heads to a finishing / towel drying area


                   P bar Y Safety Consultants Alberta Canada
       Applicable OSHA Standards
• Employers must conduct a workplace hazard
  assessment
• PPE
  – Adequate hand / eye / body protection when
    handling corrosive chemicals and manual spraying
    of treatment chemicals




                 P bar Y Safety Consultants Alberta Canada
              OSHA Standards
• Lock out / Tag out
  – In-house or vendor mechanic that maintains the
    equipment
  – Repair, replacement or maintenance of conveyor
    chains, spinner brush belts or parts, motor belts
    or repair of electrical motors or equipment




                 P bar Y Safety Consultants Alberta Canada
              OSHA Standards
• Egress/exits
  – Whether full or exterior service, safe egress must
    be maintained from one end of the tunnel to the
    other, or from all areas employees may work
  – Space may be limited and egress and exit use
    must be maintained without obstructions or locks




                 P bar Y Safety Consultants Alberta Canada
             OSHA Standards
• Eye and body wash provisons
  – Read the MSDS
  – Garden hoses with regular water pressure may be
    used for body drenching
  – An eye wash, at a minimum, must be available to
    employees




                 P bar Y Safety Consultants Alberta Canada
               OSHA Standards
• Slips, trips and falls
   – Along egress pathways and in other areas, water,
     soap and slippery chemicals can accumulate
   – Mats or rough surfacing materials can be used in
     problem areas
   – Cleanliness must be maintained




                  P bar Y Safety Consultants Alberta Canada
              OSHA Standards
• Noise and hearing conservation
  – All machinery in a wash tunnel is inherently noisy,
    particularly the blowers
  – For employees stationed near blowers for an
    extended period of time, the employer must
    conduct a noise survey




                  P bar Y Safety Consultants Alberta Canada
              OSHA Standards
• Equipment maintenance
  – All equipment must be maintained according to
    manfacturer requirements
  – Equipment used while in disrepair may break and
    project objects causing struck-by injuries
  – The digital control system may include safety shut-
    off controls and devices - it must work as designed
    and be properly maintained


                  P bar Y Safety Consultants Alberta Canada
            Combustible Fluids
• Protect yourself from sharp edges and protruding
  parts. Wear gloves and cover sharp objects with
  tape, rags or wooden guards. Steer clear of
  electrical devices like lights and outlets. You can
  easily cause a short circuit or break them. Never
  use an electric powered washer in the rain as an
  electrical short circuit could happen. If you are
  using a gas power washer inside the building or
  house, make sure it is vented properly since the
  exhaust gases can be harmful to humans when
  exposed to such gases for longer periods.

                  P bar Y Safety Consultants Alberta Canada
             OSHA Standards
• The employer should establish danger zones
  at entry and exit points where either a
  customer driver or employee driver can strike
  a worker
• Use of high visibility clothing is recommended




                P bar Y Safety Consultants Alberta Canada
                                          PPE
Protective clothing
•• Cover your body, head, neck, arms, and legs with apparel suitable for the
environment and work process, such as:
–– A rain suit with a hooded jacket and bib pants to protect from water and chemicals
–– Flame-resistant clothing for working with flammable or combustible materials
–– Non-conductive clothing when working in a potentially explosive atmosphere
–– Waterjet-resistant suit when there is a risk of contact with the waterjet
•• Wear high visibility apparel when high pressure washing on or near roadways and
mobile equipment.
•• Consider using:
–– Knee pads when working in the kneeling position
–– Padding to reduce pressure caused by resting the jetting gun on your shoulder or
hip
–– Barrier cream on your hands, arms, face, and the back of your neck to protect your
skin from chemical
exposure


                             P bar Y Safety Consultants Alberta Canada
     Put it on




P bar Y Safety Consultants Alberta Canada
Hearing protection
•• Wear earplugs or earmuffs to protect your hearing.
Noise-induced hearing loss results from a combination of high sound levels and
extended periods of exposure to sound above 85 decibels (dBA). Typical noise levels
from high pressure washing activities are 90 to 93 dBA.

Respiratory protection
•• If you are exposed to breathing hazards such as caustic or acidic products, you must
wear a respirator
providing an adequate level of protection. Consider using a full facepiece respirator to
provide respiratory, eye, and face protection. Talk to your employer to ensure you are
wearing and are properly fitted with the right respirator for the job.

Fall protection
•• Use a fall protection system when there is a risk of falling, such as on a roof, ladder,
or scaffold, or near a floor opening or skylight. A fall protection system can prevent
you from falling, or it can protect you by stopping a fall. Check with your employer
whether you are required to wear personal fall protection equipment.

Personal hygiene
•• Remove your protective clothing before coffee and meal breaks, and wash your
hands and face thoroughly before you eat, drink, or smoke.
•• Eat, drink, and smoke only in areas free of contamination.

                               P bar Y Safety Consultants Alberta Canada
               OSHA Standards
