1Which Ghanaian legislation establishes the legal framework for occupational safety, health, and welfare standards on construction sites?

A.The Environmental Protection Agency Act, 1994 (Act 490)

B.The Factories, Offices and Shops Act, 1970 (Act 328)

C.The Workmen's Compensation Act, 1987 (PNDCL 187)

D.The Ghana National Fire Service Act, 1997 (Act 537)

Explanation: The Factories, Offices and Shops Act, 1970 (Act 328) is the primary legislation in Ghana regulating occupational safety and health. It mandates safety standards, inspections, and hazard prevention in factories and construction workspaces. While other acts cover compensation or environmental impacts, Act 328 is the core safety authority.

2According to safe construction practices in Ghana, when must an erected scaffold on a masonry site be inspected?

A.Only when the project reaches the practical completion stage

B.Before first use, after any alterations, and after exposure to adverse weather conditions

C.Once every three months by the main contractor's site surveyor

D.Only after an accident or structural failure has occurred on-site

Explanation: Scaffolding must be inspected by a competent person before it is first put into use to ensure structural stability. Additionally, it must be re-inspected following any modifications or severe weather events like heavy storms to prevent collapse. Routine checks ensure the safety of masonry workers working at heights.

3What is the primary hazard to a mason's skin when handling wet cement mortar without gloves?

A.Severe chemical burns and allergic contact dermatitis due to the high alkalinity of cement

B.Skin discoloration due to the high iron oxide content in local clay bricks

C.Mild bacterial infections caused by microorganisms in sand

D.Dehydration from the evaporation of curing water on the skin

Explanation: Wet cement is highly alkaline with a pH of around 12 to 13. Direct contact can cause severe chemical burns (cement burns) and allergic contact dermatitis, often driven by hexavalent chromium compounds in the cement. Masons must always wear appropriate protective gloves to prevent skin exposure.

4Which class of fire involves combustible materials such as timber scaffolding and wood formwork on a masonry site?

A.Class A fire

B.Class B fire

C.Class C fire

D.Class D fire

Explanation: Class A fires involve ordinary solid combustible materials such as wood, paper, cloth, and plastics. On a construction site, timber scaffolding, timber formwork, and packaging are major Class A fire risks. These fires are typically extinguished using water or dry chemical powders.

5What safety measure is mandatory when excavating a foundation trench deeper than 1.5 meters on a construction site in Ghana?

A.Providing a temporary plastic dust sheet over the trench floor

B.Installing timber shoring or battering the trench sides to prevent collapse

C.Flooding the trench with water to compact the subgrade before masonry work

D.Decreasing the width of the trench to increase lateral soil pressure

Explanation: Trenches deeper than 1.5 meters present a significant risk of cave-ins, which can trap and suffocate workers. Installing timber shoring (struts and sheets) or battering (sloping) the trench sides prevents soil movement. Safe access ladders must also be provided at regular intervals.

6What is the meaning of a blue, circular safety sign displayed on a Ghanaian building site?

A.Danger or high-risk warning

B.Mandatory action (e.g., must wear safety helmet)

C.Prohibition (e.g., no entry)

D.Safe conditions and emergency exit routes

Explanation: Safety signs are color-coded to communicate messages quickly. Blue circular signs indicate mandatory actions that workers must take, such as wearing personal protective equipment. Red signs denote prohibition, yellow signs warn of hazards, and green signs indicate safe conditions.

7At what height must a mason wear a full-body fall arrest harness connected to a secure anchor point on a construction site?

A.Only when working above 10 meters

B.When working at a height of 2 meters or above where there is a risk of falling

C.Only when working on roofs with a slope greater than 45 degrees

D.Harnesses are never required if the scaffold has guard rails

Explanation: Falls from heights are a major cause of construction fatalities. Standard regulations require fall protection, including harnesses and lifelines, when working at or above 2 meters if other collective protections like guard rails are missing or insufficient. It is crucial to anchor to a load-bearing point.

8What is the long-term respiratory risk associated with continuous inhalation of fine dry cement dust and silica sand dust on construction sites?

A.Cardiovascular blockages due to calcium deposits in veins

B.Occupational asthma, bronchitis, and silicosis (scarring of lung tissue)

C.Temporary carbon monoxide poisoning

D.Gastrointestinal tract inflammation

Explanation: Dry cement dust contains calcium oxide and silica. Inhaling these fine particulates over long periods causes severe respiratory diseases, including chronic bronchitis, occupational asthma, and silicosis (permanent lung scarring). Using dust masks and wet-cutting blocks reduces dust inhalation.

9If wet cement or mortar splashes into a worker's eyes, what is the immediate first aid response required on-site?

A.Rubbing the eyes vigorously with dry cement paper bags to absorb moisture

B.Flushing the eyes immediately with clean water for at least 15 minutes and seeking medical attention

C.Applying vinegar or lemon juice to neutralize the alkaline cement

D.Covering the eyes with a dry bandage and continuing block laying

Explanation: Alkaline burns from cement are highly destructive to eye tissue. The immediate treatment is to flush the eyes with copious amounts of clean water for 15 minutes to dilute and wash away the cement particles. Rubbing or using acid neutralizers like vinegar can cause further chemical or physical damage.

10How should petrol and diesel fuel for site equipment (like concrete mixers and generators) be stored to comply with site safety standards?

A.In open plastic buckets placed near the exhaust of the running mixer

B.In approved metal safety containers stored in a well-ventilated, secure area away from ignition sources

C.In glass bottles placed on top of cement stacks to keep them dry

D.Inside the main lunchroom area to prevent theft by site workers

Explanation: Fuel is highly volatile and poses a major fire hazard. Storing it in approved safety cans inside a dedicated, ventilated fuel store prevents vapor accumulation and accidental ignition. Proper storage also prevents environmental contamination from spills.
