7.4 Control Measures

Question 1

What does ERIC SP stand for?

Answer 1

 Eliminate the hazard  Reduce exposure or risk  Isolate people from the hazard  Control exposure to the hazard  Safe Systems of Work  Personal Protective Equipment (PPE)

Question 2

What is being described below:“a formal procedure which results from a systematic examination of a task in order to identify all the hazards. It defines safe methods to ensure that hazards are eliminated or risks minimised.”

Answer 2

safe system of work

Question 3

There are two broad categories of RPE, what are they?

Answer 3

respirators and breathing apparatus (BA)

Question 4

The key factors in selecting appropriate RPE are:

Answer 4

 The level of oxygen present in the air to be breathed; and  The presence of toxic chemicals that may pose an imminent risk to life

Question 5

What is being described below:the level of respiratory protection that can realistically be expected to be achieved in the workplace by 95% of adequately trained and supervised wearers using a properly functioning and correctly fitted respiratory protective device

Answer 5

Assigned protection factor (APF)

Question 6

How is the APF calculated

Answer 6

under test conditions by dividing the level of air borne contamination by the level that would be breathed in (i.e. after the RPE has done its job).

Question 7

The minimum protection required (MPR) from specific RPE can be calculated by…

Answer 7

measuring the workplace concentration outside the facepiece of the RPE and dividing it by the maximum allowable concentration inside the facepiece of the RPE (i.e. the WEL).

Question 8

What is being described below:takes contaminants (dusts, mists, gases, vapour or fumes) out of the air so that they can’t be breathed in

Answer 8

A local exhaust ventilation (LEV) system

Question 9

The basic components of an LEV system are:

Answer 9

InletDuctworkFilterFan

Question 10

LEV systems require an annual thorough examination and test by a competent person. CoSHH allows how long between tests?

Answer 10

14 months

Question 11

What is being described below:the ongoing assessment and / or medical examination of an employee at regular intervals to determine the employees’ health state in the context of exposure to occupational health hazards.

Answer 11

Health surveillance

Question 12

Examples of Health Surveillance include:

Answer 12

 health questionnaires;  lung function tests;  skin inspections; and  blood / urine analysis.

Question 13

What is being described below:a subset of health surveillance which involves the measurement and assessment of workplace agents or their metabolites (substances formed when the body converts the chemical) in exposed workers. Measurements are made either on samples of breath, urine or blood, or any combination of these.

Answer 13

Biological monitoring

Answer 14

Asthmagens

Question 15

chemicals that may cause cancer or increase its incidence are known as

Answer 15

Carcinogens

Question 16

chemicals that induce heritable genetic defects or increase their incidence are known as

Answer 16

Mutagens
