Foundations of HSE Engineering Explained Through Practice

Foundations of Health, Safety, and Environmental Engineering

Purpose

This handout connects core HSE engineering concepts to practical workplace examples, high lighting how correct application prevents incidents and mitigates risks. It includes targeted analytical questions to develop strategic decision-making, problem-solving, and competency-based skills.

Section 1: Core HSE Concepts and Workplace Application

Concept	Description	Workplace Example (UK context)	Competency Application
Hierarchy of Risk Control	Structured approach to eliminate or minimize risks	A construction site installs fume extraction systems to remove welding smoke instead of relying solely on PPE	Evaluate and implement multilevel controls across projects
ALARP Principle	Risks reduced to As Low As Reasonably Practicable	Chemical storage tanks are equipped with containment systems, alarms, and training, balancing cost and safety	Strategic risk evaluation, costbenefit analysis, compliance with HSWA 1974
Hazard Identification	Recognizing sources of harm	Manual lifting tasks assessed for ergonomics, using lifting aids and rotation schedules	Identify hazards, implement administrative and engineering controls
Human Factors	Consideration of fatigue, cognition, training, and behavior	A shift schedule is modified to reduce fatigue-related errors in a refinery	Incorporate human reliability assessment into risk planning
Environmental Impact Assessment	Evaluating effects of engineering activities on air, water, soil	Wastewater discharge from an industrial plant is treated and monitored to prevent contamination	Design mitigation measures and ensure compliance with Environmental Protection Act 1990
Incident Reporting & Investigation	Recording and analyzing accidents or near misses	A minor gas leak triggers immediate reporting and investigation, leading to system upgrades	Develop lessons learned and continuous improvement in safety systems
Emergency Preparedness	Planning responses to hazardous events	Fire drills, spill response plans, and emergency evacuation routes in chemical plants	Assess procedures and train staff to maintain readiness
Legislative Compliance	Understanding and adhering to UK HSE law	CDM 2015 ensures safe project design; COSHH 2002 ensures safe chemical use	Apply legal frameworks to operational planning and audits

Section 2: Risk Control Concept in Practice

Workplace Scenario – Welding Operations

Hazards Identified: Fumes, UV radiation, hot surfaces, fire risk
Control Measures Applied:
- Engineering: Local fume extraction, fire-resistant screens
- Administrative: SOPs, regular inspection, permit-to-work system
- PPE: Welding helmets, gloves, respirators
Outcome: Reduced incidence of respiratory illness and burns

Strategic Reflection (Level 7 Focus):

Evaluate cost, efficiency, and compliance of controls
Consider long-term implications on workforce health, environmental impact, and regulatory risk

Section 3: Environmental Management in Engineering

Concept	Example	Level 7 Competency Application
Waste Management	Segregating and disposing of hazardous and non-hazardous waste at a chemical plant	Integrate ISO 14001 standards into operational planning
Pollution Prevention	Installing air scrubbers to control emissions from boiler stacks	Monitor emissions and align with Environmental Protection Act 1990
Resource Conservation	Recycling water in manufacturing processes	Strategic design of processes to minimize environmental footprint
Incident Mitigation	Containment bunds around chemical storage tanks	Evaluate multi-level controls and maintain regulatory compliance

Section 4: Human Factors and Organizational Safety Culture

Human Factors Considered in HSE Engineering:

Fatigue and shift patterns
Competency and training of personnel
Communication failures in complex engineering systems

Workplace Example:

In a UK refinery, rotating shifts and mandatory breaks reduced operator fatigue-related errors by 30%.
Clear reporting channels enabled early identification of procedural risks.

Level 7 Analysis:

Design safety programs that consider behavioral science, cognitive load, and team dynamics
Implement training and reporting structures to support strategic HSE objectives

Section 5: Incident Analysis and Learning

Example: Minor spill in a chemical processing unit

Immediate Action: Containment, isolation, and reporting per COSHH 2002
Investigation: Root-cause analysis identified improper valve maintenance
Corrective Action: Scheduled maintenance, updated SOPs, staff training
Strategic Outcome: Reduced risk of recurrence, enhanced compliance, improved environmental monitoring

Reflection: Understanding incident causes improves decision-making and preventive strategies across projects.

Section 6: Analytical and Strategic Questions

In a high-risk project involving welding and chemicals, how would you prioritize control measures using Hierarchy of Risk Control?
How can ALARP principles be applied across multiple sites to balance safety and operational efficiency?
Identify three human factors risks in engineering operations and propose practical mitigation strategies.
Describe how environmental impact assessments inform design decisions in UK engineering projects.
A near-miss occurs due to equipment failure. What steps should be taken to prevent future incidents, and how would you communicate lessons learned to stakeholders?
