Safety
Workplace health and safety (WHS) requirements need to be observed in accordance with legislation. You need to know the WHS laws governing your job. Revision of CPCPCM2043A – Carry out WHS requirements, before commencing this unit is advisable.
In any work situation you can reduce the risk of injury to yourself and others by using appropriate personal protective equipment (PPE). The types of PPE that you will need include:
· overalls – used for the protection of the installer when working in different conditions
· boots – it is recommended that soft soled footwear is worn while working on roofs, as deep grooved footwear pick up small stones and debris that might damage or scratch the roof sheets
· safety glasses or goggles to protect the eyes from injury when cutting the materials with a power saw
· ear plugs or muffs to protect the installer’s hearing from excessive noise
· dust masks or respirators to protect the user from breathing in dust or fine particles when cutting the material with a power saw
· gloves, for the protection of the installer’s hands when working with different types of pipes, tools and equipment.
Workplace environment and safety
Handling of materials / Manual lifting and handling techniques must always be followed according to WHS requirements. You should move materials into position by hand where possible. Excessive manual handling should be avoided and cranes and other mechanical lifting devices should be employed when necessary.Limited height scaffolds and elevating work platforms (EWP) / Operators must ensure they are familiar with all operating procedures detailed by manufacturers in the elevated working platforms operators’ manual. Personal protective equipment must be worn at all times by the person working in the basket of the EWP. This consists of safety harnesses, safety helmets, rubber soled shoes, safety vests and suitable clothing.
Introduction
In this unit you will look at how pre-treatment facilities are used to intercept and retain prohibited discharges.
Prohibited discharges can include:
· Grease
· Fats
· Acids
· Solvents
· Oils
· Plaster
· Clay
· Hot water (over 38°C)
· Sand, silt, grit and dirt
· Other solids.
Pre-treatment facilities are installed and designed to intercept and retain prohibited discharges from the sewage system. Sewage is considered to include human waste and wastewater from domestic wastewater fixtures. This includes waste from the bathroom, kitchen and laundry areas. Any other discharge is classified as a prohibited discharge and therefore must have some form of
pre-treatment prior to discharging to the sewerage system.
Why pre-treatment?
There are a number of reasons why a pre-treatment facility should be used. Some of the reasons include:
· Discharge such as acid may cause damage and corrosion to the drains manholes and destroy bacteria that helps in sewage treatment
· Substances like grease, if not collected in a grease arrestor, will solidify in the drain and cause a blockage
· Chemicals may give off toxic gases that can be harmful to workers maintaining and operating the sewerage system.
Prepare for work
Plans or specifications are obtained from job supervisor
Before you begin you need to obtain the plans or specifications or design drawings for the task and other relevant information from the local authorities in regards to the installation of a pre-treatment facility. Gathering this information will help you to make informed decisions about the nature of the task and how to plan and sequence the entire process. Some of this may be available from your job supervisor or trainer.
WHS requirements associated with installing pre-treatment facilities, and the workplace environment, are adhered to throughout the work
Workplace health and safety (WHS) requirements need to be observed in accordance with legislation. You need to be aware of the WHS laws governing your task. Your trainer or supervisor can provide you with this documentation.
Workplace health and safety requirements are to be in accordance with State or Territory legislation and in some cases may require work notices to be submitted. These may include:
· wearing of personal protective equipment (PPE) and clothing
· use of tools and equipment
· workplace environment and safety
· handling of materials
· handling of hazardous materials
· hazard control.
· trench support
· working with machinery
· installing bunting
Quality assurance requirements are identified and adhered to in accordance with workplace requirements
Most companies have a policy for assuring quality to the customer. This policy is designed to:
· Control the processes used within the company
· Make sure that records are kept
· Control the quality of materials used
· Standards to which the work has been completed
· You need to be aware of your company’s particular quality assurance requirements. A number of quality assurance issues are dealt with in the next section. In general follow these guidelines when completing your work.
Tasks are planned and sequenced in conjunction with others involved in or affected by the work
You should always consider other trades when planning your work because that the installation process is likely to affect other tradespeople on-site. Considering others is particularly important when you are installing a large facility that has public safety implication.
The installation of large pre-treatment facilities is likely to require machinery to dig the hole required. In doing so it will restrict access to the area. Therefore the installer must ensure, prior to starting the task, to consult with the other trades or affected persons.
