Advanced Certificate in Health Safety & Environment- Level 3

Explore the classification of confined spaces by distinguishing permit required, non permit, and alternate permit spaces and their hazards with examples like manholes and trenches.

Explains the five steps—isolate, ventilate, complete the permit, test the atmosphere, and enter—and the supervisor-approved safety procedures for permit-required confined space entry.

Discover roles and responsibilities in confined space entry, including entrant duties to ventilate, isolate, exit on command using PPE; attendants monitor access and hazards, while supervisors verify permits and training.

Apply the permit to work system as an administrative control to identify hazards, assess risks, and implement controls, ensuring safe isolation and clear communication for hazardous jobs.

Training in permit to work builds competence and risk awareness to manage hazards and controls. It covers system principles, permit types, documentation, signatory competence, authorization expiry, refresher training, and record-keeping.

Authorize and issue permits after hazard and control discussions. Display, monitor, revalidate, and manage shift handovers, emergency actions, and records.

Assess machine hazards and implement guards using the OSHA hierarchy of controls. Involve operators and supervisors to design durable, secure guards that prevent contact, allow lubrication, and avoid new hazards.

Explore presence sensing devices such as photoelectric, radio frequency, and safety mats, with two-hand control pullbacks and restraints, movable barriers, and safety trip controls to stop or prevent machine operation.

Explore how to prevent workplace fires by planning a comprehensive fire safety program, training staff, selecting appropriate extinguishers, and establishing an emergency action plan for safe egress.

Trace how fire safety legislations emerged from historic fires and how NFPA 704 identifies hazardous materials, while the fire tetrahedron—heat, fuel, oxygen—explains extinguishing methods and OSHA fire safety regulations.

Identify fire extinguisher for different fire classes and hazards, guided by a chart mapping extinguishers to A, B, C, D, and electrical fires, and NFPA light, ordinary, and extra hazards.

Examine personal protective equipment as the last line of defense in the hierarchy of controls, covering eye and face, head, food, hand, and respiratory protection, plus a case study exercise.

Identify hazards and require eye and face protection for flying particles, molten metal, and chemical vapors. Ensure protectors meet hazard-based minimums and include prescription and filter lenses with manufacturer identification.

Identify when to wear hard hats to prevent head injuries and electrical shocks, and learn ANSI type and class ratings (type 1, type 2, E, G, C) and labeling.

Conduct a hazard assessment to determine appropriate hand protection, then select PPE based on task hazards and conditions, and understand standards for glove testing and protection levels.

Explore toxicology and exposure concepts, including how duration and concentration shape worker risk and routes of entry. Apply exposure limits such as IDLH, TLV, TWA, STEL, PEL, LD50, LC50.

Explore electrical hazards, their effects on the body, and the use of protective devices. Follow training guidelines to safeguard your organization from electrical hazards, with a case study and exercises.

Learn to protect circuits with fuses, circuit breakers, and GFCIs, and understand overcurrent, overload, and fault concepts to prevent shock and equipment damage.
