In this action verb Nebosh will normally ask types , reasons or else categories in syllabus Question: Identify three types of legal duties that the employer has to comply with? In this type of question you no need to explain the key features , simply mentioning is enough.

Outline the common duties of employees???? Reasonable care: To take reasonable care of themselves and others safety Reporting of hazards: To report to the supervisor regarding imminent hazards, if any found Co-Operate with employer: This is a particular problem when the load is a container full of smaller items.

There must be suitable means of access such as scaffolding. The position of the centre of gravity is important for stable lifting — it should be as close to the body as possible.

The imposition of a high rate of work is a particular problem with some automated production lines and can be addressed by spells on other work away from the line. There should not be excessive pulling. The state of floor surfaces and the footwear of the individual should ensure that slips and trips are avoided.

Sometimes the contents of the load are likely to shift. If the loads are handled whilst the individual is seated.

Protection should be provided in the form of covers where people work near to fragile materials and roof lights. If the load is too bulky or unwieldy. The means of transporting materials to and from the roof may require netting under the roof and even weather protection. These are glass components which may shatter if dropped and leave shards of glass to be carefully cleared up.

The frequency of lifting. The load should not be carried over excessive distances greater than 10 m. They should be allowed to cool sufficiently. The particular hazards are fragile roofing materials. There is therefore no safe load but guidance is available from HSE literature.

The load is likely to be hot and could be sharp as well in places or when broken so that personal protective equipment. Visibility around the load is important. Working in a vehicle repair garage without proper ventilation to exhaust gases would expose a person to carbon monoxide fumes.

The virus can be transmitted from infected faeces Hepatitis A or by infected blood Hepatitis B and C. When these sites are disturbed. It is good practice to ensure that a person does not work alone on a roof. People working on these systems or working in the area of infected systems are at risk. This can lead to asbestosis scaring of the lungs.

Precautions will be required for other hazards associated with roof work. The most common occurrence of carbon monoxide is in exhaust gas from a vehicle engine. Asbestos can be found in buildings. It causes headaches and breathlessness and at higher concentrations unconsciousness and death. The three most common systems at risk from the bacteria are water systems that incorporate a cooling tower. It produces a form of pneumonia caused by the bacteria penetrating the alveoli in the lungs.

Hospital workers and first aiders who come into contact with blood products are at risk of hepatitis.
