Physicochemical hazards  May decompose above 40°C, in sunlight or in contact with acids.  Also reacts with oxidisable materials, heavy metals (which act as catalysts), reducing agents, ammonia solutions, ether, and many organic and inorganic chemicals such as paint, kerosene, paint thinners, shellac, grease and oils.  May liberate chlorine gas on decomposition.

Who is exposed:
All cleaners are involved in the mixing and application of Zap.

Frequency and duration of exposure:
Mixing (dilution) is done once at the start of each shift. It takes approximately a minute to perform this task.  Workers use the working strength solution for 4 hours a day, 5 days a week.

Controls already in place:
    * Cleaners are provided with training on the hazards of using the chemicals, including correct storage locations.
    * Cleaners are provided with rubber gloves.
    * There is good general ventilation in the storeroom.
    * Eating, smoking and drinking is prohibited in the storeroom. Signs to this effect are displayed.
    * Washing facilities are available in the storeroom and in the areas where Zap is used.
    * Only non-metallic plastic containers are used for mixing and it is stored indoors away from direct sunlight.

Task             Routes of exposure                                                                                          Risk to health? (Yes/No/Not sure)

Mixing           Skin/eyes                                                                                                     YES:
                                                                                                                               •  Handling of the concentrate presents the greater risk –particularly to skin and eyes.
                                                                                                                               •  Splashes to the skin and face have occurred occasionally
                                                                                                                               when decanting concentrate.

Inhalation         NO:
                   •  Exposure through inhalation does not present a risk to health due to the short duration of the task.
                   •  Adequate general ventilation.
                   •  Potential for generating fine spray mist during this task is negligible.

Inhalation         YES:
                   •  When working in confined, poorly ventilated areas.
                   •  Fine spray mist generated by spray applicator.

Risk control actions:
    * Purchase the concentrate in containers fitted with a dispenser (tap) to minimise the potential
      for spills and splashes during decanting. Hang a small plastic container under the tap dispenser to contain any drips. Alternatively, an automatic dilution and dispensing system may be installed to avoid contact with the concentrate.
    * Use a more dilute working strength solution. The directions for use on the label recommend a concentration of 1-2% for this type of application. Cleaners have been using a more hazardous 5% working strength solution. The reason for this is not known.
    * Use a coarse spray applicator to reduce the potential for exposure through inhalation.
    * Make
