HSE Level 3: Advanced Health, Safety & Environment Cert

Define a confined space by three criteria: large enough to enter and work, limited entry, and not designed for continuous occupancy; recognize risks of oxygen deficiency and entrapment.

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.

Review site-specific confined spaces and hazards, then implement a permit-based entry program with site-specific permits, ppe, respirator use, and on-site emergency procedures.

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.

Define areas of responsibility and establish authority levels by assigning authorized permit signatories. Maintain a plot plan and records, and ensure managers delegate only to competent assessed signatories.

Outline the essential features of a permit to work form, including clear description of the work with plant and equipment, attachments, operational preparations, hazard details, precautions, authorization, validity, and hand-back.

Monitor permit-to-work operations daily with spot checks on sites, permits, and documents. Audit and review the system regularly with assessors, retain permits and risk assessments on site for 30 days.

Prepare to deploy the permit to work system by planning non-routine tasks, validating the job hazard analysis, arranging isolations and clearance of process materials, and certifying lockout tagout readiness.

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

Learn about loto devices, including tags, locks, and devices that make energy isolation equipment lockable, and explore safety padlocks, hasps, lockouts for valves, circuit breakers, plugs, and sockets.

Master seven-step loto procedures for machine-specific energy control, covering preparation for shutdown, shutdown, isolation, blocking, release of stored energy, verification, and re-energization, with documented procedures and lessons from real cases.

Explore why machine guarding matters and how safeguards protect workers from rotating, reciprocating, and transverse motions and hazardous actions such as cutting, punching, shearing, and bending.

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 four guard types—fixed, interlocked, adjustable, and self-adjusting—and how each blocks danger areas, with fixed as permanent and interlocks that trip when opened.

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.

Develop a proactive safeguarding program for machines with guards, devices, training, PPE, and safe operating procedures under supervision. Use the checklist to ensure guards prevent contact and enable safe 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.

Learn how to implement an emergency action plan with three fire protection options, train staff, and maintain extinguishers, while ensuring compliant exit routes per regulation 19 1036.

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.

Assess hazards, select and fit PPE per OSHA 1910.132, and ensure training, maintenance, and disposal. Explain EPA levels of protective clothing from level A to D and associated respirator use.

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 respiratory protection essentials, detailing respirator types—from air purifying to atmosphere supplying—fit testing and hazard assessment to select appropriate respirators for safety.

Learn how the OSHA hazard communication standard safeguards chemical safety through labeling, safety data sheets, worker training, and a written program, aligned with the global harmonized system.

Identify hazard communication duties under the GHS-aligned HCS, including manufacturers, importers, and distributors classifying hazards and preparing labels and SDSs; employers implement a written hazard communication program and train workers.

Understand hazard communication classification, physical and health hazards, and GHS labeling. Examine NFPA, HMIS, WHMIS systems and the role of labels and safety data sheets.

Train workers on the properties of hazardous materials, read labels and the SDS, and understand OSHA, DOT, EPA, and NRC regulations to manage chemical safety.

Examine how physical state influences hazard potential and master hazmat properties, including flash point, boiling point, vapor pressure, solubility, specific gravity, vapor density, and the interpretation of labels and SDS.

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.

Identify the hazards of electricity and how to prevent injuries to workers, including electric shock, burns, arc blasts, explosions, and fires, with emphasis on OSHA standards and safe work practices.

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