Identify chemical hazards and their routes of exposure, recognize signs of overexposure. Apply worksite analysis, interpret exposure limits (PEL, TLV), and implement the hierarchy of controls and hazard communication.

Identify the four main chemical hazard forms: solids, liquids, gases and vapors, and aerosols, and how exposure occurs by inhalation, skin contact, or ingestion, with ventilation and respiratory protection guidance.

Identify the four primary routes of entry (inhalation, ingestion, absorption, and injection) through which chemicals enter the body, with inhalation as the most common route.

Identify how lead exposure harms organs through inhalation or ingestion of dust in painting, battery work, welding, demolition, and review OSHA controls like air monitoring and blood lead level testing.

Explore OSHA's hierarchy of controls for industrial hygiene, from elimination and substitution to engineering, administrative controls, and PPE, to reduce worker hazards.

Learn how PPE provides a final layer of protection against hazards, with respirators, gloves, eye protection, and protective clothing chosen for chemical, heat, and splash risks.

Explore physical hazards in the workplace, including heat and cold extremes, noise, vibration, radiation (ionizing and non-ionizing), and illumination, and learn how these factors impact health and safety.

Protect workers from heat exposure with a layered strategy of engineering and administrative controls. Adopt cooling, ventilation, acclimatization, water intake, rest cycles, schedules, rotation, regular monitoring, and an emergency plan.

Define ergonomics as fitting the job to the worker by designing workstations, tools, and equipments to support the body and natural movements, enhancing safety, comfort, and efficiency.

Explore why ergonomics matters for preventing injuries from overexertion, slips, trips, and repetitive motions, and how addressing small strains saves costs and protects long-term health.

Employees must follow OSHA safety standards, own their safety, and report early red flags—persistent pain, numbness, or white fingers—to protect themselves and the workplace.

Recognize early warning signs of musculoskeletal disorders, such as mild back, neck, shoulder, or wrist discomfort and numbness, and report them to address ergonomic risks and prevent progression.

Identify environmental ergonomic hazards that amplify musculoskeletal disorders (MSDs) by affecting fatigue, posture, and coordination; learn how lighting, temperature, and visibility interact with tasks to protect worker health.

A job hazard analysis breaks a task into steps to identify hazards and record control measures, serving as a planning and communication tool for safer work and ergonomic risk reduction.

Learn work practices controls as the human-centered line of defense against musculoskeletal disorders by adopting safe habits, proper lifting, task rotation, micro breaks, tool use, and tidy workspaces.

Remove obstacles and use equipment to raise or lower items, keeping tools within reach and elevating work areas to prevent overhead reaching musculoskeletal injuries to shoulders, neck, and upper back.
