and the direction of the stream of ventilating air influences how coating is applied, and
    * easy the object is to move and whether work systems and plant could be improved.
Appendix A contains an example of a risk assessment that can be used as guidance when assessing the risks involved with spray painting or powder coating activities including associated activities.

Monitoring airborne contaminant levels

Regulation 50 A person conducting a business or undertaking at a workplace must ensure that
air monitoring is carried out to determine the airborne concentration of a substance or mixture
at the workplace to which an exposure standard applies if:
    * the person is not certain on reasonable grounds whether or not the airborne concentration
      of the substance or mixture at the workplace exceeds the relevant exposure standard; or
    * monitoring is necessary to determine whether there is a risk to health.
The results of air monitoring must be recorded and kept for 30 years after the date the record
is made.
Air monitoring is the sampling of workplace atmospheres to obtain an estimate of workers' potential inhalation exposure to hazardous chemicals.
Air monitoring can be used:
    * when there is uncertainty about the level of exposure
    * to indicate whether the exposure standards are being exceeded or approached, and
    * to test the effectiveness of the control measures.
Air monitoring should be carried out by a person such as an occupational hygienist with skills
to carry out the monitoring according to standards and to interpret the results. Where monitoring
of airborne contaminants is used to determine a person's exposure, the monitoring must be undertaken in the breathing zone of the person.
Results from air monitoring indicate how effective your control measures are, for example whether ventilation systems are operating as intended. If monitoring identifies that the exposure standard
is being exceeded, the control measures must be reviewed and any necessary changes made.
Air monitoring cannot be used to determine a risk to health via skin contact of airborne chemicals.
Further guidance on Exposure Standards is available in the publication Workplace Exposure Standards for Airborne Contaminants.

2.3 Controlling the risks

The hierarchy of control measures
Some control measures are more effective than others. Control measures can be ranked from
 the highest level of protection and reliability to the lowest. This ranking is known as the hierarchy of control.
You must always aim to eliminate a hazard and associated risk first. If this is not reasonably practicable, the risk must be minimised by using one or more of the following approaches:
    * Substitution – for example:
       * use a water-based paint instead of an organic solvent based coating
       * use a brush or roller instead of
