  • Use personal protective clothing or equipment such as neoprene gloves, rubber boots, shoe covers, rubber aprons, and protective eyewear, when using chemicals labeled "Flammable", "Corrosive", Caustic" or "Poisonous"
  • Always use your chemical goggles and the face shield when handling chemicals labeled "Corrosive" or "Caustic"
  • Do not use protective clothing or equipment that has split seams, pin holes, cuts, tears, or other visible signs of damage
  • Each time you use your gloves, wash them, before removing the gloves, using cold tap water and normal hand washing motion; always wash your hands after removing the gloves.

  1. Only use the red color-coded, plastic or metal containers for transferring the liquid.
  2.  Electrically ground and bond the containers as follows:
  • a) Attach the clip at one end of the grounding wire to the rim of the dispensing container and then attach the clip at the other end of the grounding wire to a ground source, such as a ground driven steel stake.
  • b) Attach the clip at one end of the bonding wire to the rim of the dispensing container and then attach the clip at the other end of the bonding wire to the rim of the receiving container.
  • c) You are now ready to dispense the liquid from the bulk container into the opened receiving container. Upon completion, replace the lid on the receiving container and remove the bonding wire.
  • Before using the chemical exhaust hood, flip the fan motor switch to the "On" position
  • Do not use chemicals from unlabeled containers or unmarked cylinders
  • Do not perform "hot work", such as welding, metal grinding or other spark producing operations, within 50 feet of containers labeled "Flammable" or "Combustible"
  • Do not drag containers labeled "Flammable"

Hand Truck Operation

  • When loading hand trucks, keep your feet clear of the wheels
  • Do not exceed the manufacturer's load rated capacity; read the capacity plate on the hand truck if you are unsure
  • Place the load so that it will not slip, shift or fall; use the straps, if they are provided, to secure the load
  • For extremely bulky or pressurized items such as gas cylinders, strap or chain the items to the hand truck
  • Tip the load slightly forward so that the tongue of the hand truck goes under the load
  • Push the tongue of the hand truck all the way under the load that is to be moved
  • Keep the center of gravity of the load as low as possible by placing heavier objects below the lighter objects
  • Push the load so that the weight will be carried by the axle and not the handles
  • If your view is obstructed, ask a spotter to assist in guiding the load
  • Do not walk backward with the hand truck, unless going up stairs or ramps
  • When going down an incline, keep the hand truck in front of you so that it can be controlled at all times
  • Move hand trucks at a walking pace
  • Store hand trucks with the tongue under a pallet, shelf, or table

Fire Extinguiser Selection

Portable fireextinguishers can saves lives and property by putting out or containing fireswithin the capability of the extinguisher. However, they must be of the correcttype for the particular fire, and they must used correctly.

Selection of Fire Extinguishers
There are a number of types of portable fire extinguishers available inAustralia. Each type of extinguisher may be rated for one or more classes offire. In some cases, particular extinguishers are not only consideredineffective against certain classes of fire, they can be dangerous if used inthose circumstances.

The classes of fire are:

Class A
: Ordinary combustibles (Wood, Paper, Plastics)
Class B : Flammable and combustible liquids
Class C : Flammable gases
Class D : Combustible metals
Class E : Electrically energised equipment
Class F : Cooking oils and fats

Portable fire extinguishers are distinguishable by their labels and theircolouring. In 1997 the standard colours of some portable fire extinguisherswere changed. It is therefore likely that you may encounter two of the sametype of extinguisher with different colourings.
