NEBOSH Health and Safety Foundations 4

Question 1

What is the 'domino theory' of accident causation?

Accepted Answer

Accidents result from a sequence of factors (social environment, fault, unsafe act/condition, accident, injury) that fall like dominoes — removing any domino prevents the injury

Answer

Heinrich's domino theory (1931) proposed that injuries result from a sequence of five factors (like dominoes). Removing the central 'unsafe act or condition' domino breaks the sequence. The theory shifted focus from blaming workers to understanding and interrupting causal sequences — foundational to modern accident investigation.

Question 2

What does 'active monitoring' of health and safety performance involve?

Accepted Answer

Regular workplace inspections, safety tours, audits, and review of risk assessments before incidents occur

Answer

Active (proactive) monitoring checks that safety controls are working before harm occurs. It includes workplace inspections, safety observations, monitoring of environmental conditions (noise, air quality), reviewing risk assessments, and auditing safety systems. It contrasts with reactive monitoring (analyzing accidents after the fact).

Question 3

What is the purpose of health and safety training for workers?

Accepted Answer

To ensure workers have the knowledge and skills to work safely, comply with procedures, and recognize and report hazards

Answer

Effective H&S training equips workers with the competence to recognize hazards, understand and follow safe procedures, use equipment safely, respond to emergencies, and fulfill their own legal duties. Without adequate training, even the best written procedures will fail in practice.

Question 4

What does an 'improvement notice' issued by a health and safety inspector require?

Accepted Answer

The duty holder must remedy a specified contravention within a given time period, or face prosecution

Answer

An improvement notice requires the duty holder to remedy a contravention of health and safety law within a specified minimum period (typically 21 days or more). The duty holder can appeal. Failure to comply with an improvement notice is a criminal offence, escalating to prosecution.

Question 5

What is the function of a health and safety policy statement?

Accepted Answer

To communicate senior management's commitment to safety, define responsibilities, and describe how safety will be managed

Answer

A written H&S policy has three parts: a statement of intent (commitment), organization (who is responsible for what), and arrangements (how the policy is implemented through procedures, training, monitoring). It is a legal requirement for employers with 5+ employees under UK law and equivalent regulations.
