* nine inch angle grinder 97 – 110 dB(A)
    * air compressor 85 – 89 dB(A)
    * inside a spray booth 75 – 91 dB(A), and
    * processes involving compressed air 93–110 dB(A)
The exposure standard for noise is defined in the WHS Regulations as an LAeq,8h of 85 dB(A)
or an  LC,peak of 140 dB(C). There are two parts to the exposure standard for noise because noise can either cause gradual hearing loss over a period of time or be so loud that it causes immediate hearing loss.

Noise control measures include:

    * removing the source of noise completely
    * substituting a noisy process or machine, such as an air compressor or extraction fan,
       with a quieter one
    * isolating the source of noise from people by using sound proof enclosures or barriers
    * using engineering controls, for example sound absorbing materials, mufflers
    * using administrative controls, for example limit the amount of time people work in noisy areas, and
    * using personal hearing protectors to protect workers from any remaining risk.
Further guidance about controlling noise or ototoxic effects in the workplace is available at
Code of Practice: Managing noise and preventing hearing loss at work.

5.7 Injection injury
Most injection injuries occur through the use of airless spraying equipment which involves
high pressure.
Paint injected into the body may initially appear harmless but may cause a lack of blood supply
to the area, or cause chemical or thermal burns. Solvents and other substances may be injected
in sufficient quantities to cause symptoms affecting the whole body.
All workers with injection injuries should be referred for immediate medical treatment to minimise the possibility of gangrene or tissue destruction, which could result in disability through amputation or death.
Injection injury control measures include:
    * using a tip guard on the spray gun
    * using a spanner to tighten the tip guard, or when clearing a blocked reversible spray tip, and
    * ensuring that the spray gun has a trigger-lock and it is functional.

APPENDIX A – SAMPLE RISK ASSESSMENT SHEET

Date: ­­­­­­­­­­­­­­                                          1 February 2012
Assessor:   Ann Person
Location:   Main spray painting and baking line
Tasks:   Paint mixing, colour matching, spraying, baking and cleaning up
Workers involved:  P. Stone and J. Saunders
Duration of work:  Approximately 1.5 hours of preparation and mixing, 5 hours spraying and 1.5 hours cleaning up

HAZARDS IDENTIFIED               Hazardous chemicals: 2-pack paint containing isocyanates (toxic, possible skin/respiratory sensitisation), thinners containing xylene (harmful by inhalation or through skin, skin irritant).
                                 Static electricity: potential contact of flammable solvents with static electricity may result in fire and explosion.
                                 Other issues: manual tasks, heat stress, visibility, noise from plant and injection injury.
