SSSTS Test 02: Risk Management & Health

SSSTS Test 02: Key Themes

This exam focuses on Operational Safety, Fire Prevention, and Occupational Health.

Confined Spaces: Never enter a confined space until the air has been tested. Testing the air after you go inside is a fatal mistake.
Electrical Safety: When isolating power, every worker needs their own lock and key. Do not rely on signs or verbal warnings alone.
Employer Duties: Employers are legally required to provide and pay for all PPE. They also must provide a warm place to eat with a way to heat food.

Q:1Which of these is NOT a safe way to control risks when you work in a confined space?
Managers must test the air before any worker goes inside. Testing the air after entry is too late and puts the person in great danger.
Q:2The locking-off of an electrical isolator often forms part of a safe system of work. Which one of the following will ENSURE that the supply cannot be re-energised until it is safe to do so?
For a system to be safe, every worker must have their own lock and key. This stops anyone else from turning the power back on.
Q:3What colour panel identifies a dry powder fire extinguisher?
Dry powder tanks have a blue label. Other colours tell you different things like black for carbon dioxide and cream for foam. Red is for water.
Q:4Which one of the following would NEED to be used prior to entering an inspection chamber?
Inspection chambers are often confined spaces where sewer gases can occur. A gas monitor is the only way to know if the air is safe.
Q:5When can a boss charge their workers for Personal Protective Equipment (PPE)?
Safety laws are very strict about this. Employers must pay for all safety gear. They can never charge a worker for the equipment they need.
Q:6What is the function of a fire marshal/warden during an emergency?
A fire marshal helps guide people out and does a sweep of the building. They make sure nobody is left behind in toilets or rooms.
Q:7Which one of the following is the MOST reliable means of establishing the safe working distance from overhead electricity cables?
The company that owns the cables knows the voltage and how far electricity can arc. They are the only ones who give a safe distance.
Q:8Who must carry out an inspection of an excavation?
A person with the right skills and training must check the hole. They must do this at the start of every shift to keep everyone safe.
Q:9Which one of the following is the cause of MOST fatalities in the UK construction industry?
Falling from height remains the number one cause of death on sites. It happens more than any other type of accident in the UK industry.
Q:10Why should timber ladders or stepladders never be painted?
Paint covers up rot and cracks. Ladders should be left natural so that a supervisor can see if the wood is failing during an inspection.
Q:11What rest facilities must a construction site provide for its workers?
The law says workers need a warm place to sit and eat. You must provide a kettle or microwave for hot food and drink.
Q:12When receiving any plant or equipment from a hire company, which one of the following documents MUST be supplied?
You cannot expect someone to use a machine safely without instructions. These must be provided so the operator knows how the machine works.
Q:13At what daily noise exposure level must Hearing Protection Zones be created?
85 decibels is the upper action value. Once noise reaches this level, the employer must provide ear protection and make sure it is worn.
Q:14Every work task on a site must have which of the following?
A risk assessment is the most important start to any job. You must find the dangers before you can tell workers how to stay safe.
Q:15Controlling the exposure to which one of the following will REDUCE the risk of occupational asthma?
Asthma is often triggered by breathing in dust or fumes that act as sensitizers. These cause the lungs to overreact, leading to breathing problems.
Q:16How often should a team test a portable RCD used on a construction site after its first use?
Building sites are rough places for electrical gear. You must do a full test every month to make sure the safety switch works correctly.
Q:17A Mobile Elevating Work Platform (MEWP) has been hired for access. What must the plant NOT be used for?
A MEWP is designed to lift people, not heavy loads. Using it as a crane can cause it to tip over or collapse.
Q:18With regard to hand-arm vibration, which of the following actions should be taken:
Reducing vibration damage requires a mix of good equipment, maintenance, and strict time limits on how long a worker uses the tool.
Q:19What is the best way to protect people if objects might still fall from a height?
A hard hat is only a last resort. It is much safer to block off the area so that no person can walk under objects.
Q:20Which one of the following is required if a person has to work alone in a remote area:
Lone working requires communication and a plan to check on the worker. If they do not check in, someone needs to find them.

Test 02 Study Summary

1. Fire Safety Blue labels mark dry powder extinguishers. A fire marshal's job is to ensure everyone has left the building during a drill or emergency.
2. Height Hazards Falls from height are the biggest killer in construction. Never paint timber ladders as it hides dangerous cracks and rot.
3. Occupational Health Noise protection zones are needed at 85dB(A). To prevent asthma, workers must avoid breathing in respiratory sensitizers like dust and fumes.
