Published by SALUS

A cement industry toolbox talk should start with hazard identification and task-based risk assessment before work begins. Review the job steps, identify dust, chemical, mechanical, ergonomic, vehicle, slip/trip, and energy-isolation hazards, then put controls in place using the hierarchy of controls: engineering controls first, administrative controls next, and PPE last. Concrete and cement work commonly involves eye, skin, and respiratory irritation from cement dust, inadequate guards, ergonomic overexertion, slips/trips/falls, chemical burns, confined spaces, and noise exposure. Workers should also identify pinch points, rotating parts, mobile equipment interaction zones, and any maintenance tasks that require lockout/tagout before starting the job. [1] [10] [11]

Key hazards to discuss with crews:

  • Cement and clinker dust exposure, including respirable crystalline silica
  • Wet cement contact causing skin irritation, dermatitis, or chemical burns
  • Eye injury from dust, splashes, and flying particles
  • Conveyors, gears, rollers, pulleys, and rotating shafts creating pinch-point and entanglement hazards
  • Unexpected startup or stored energy during cleaning, maintenance, or jam clearing
  • Manual handling injuries from bags, tools, hoses, forms, and awkward postures
  • Slips, trips, and falls from spills, rebar, uneven walking surfaces, and poor housekeeping
  • Struck-by hazards from mobile equipment, pump booms, chutes, and reversing vehicles

[2] [2] [10] For PPE, require equipment that matches the task and exposure. At a minimum in cement handling areas, workers typically need hard hats, safety glasses or goggles, gloves, protective clothing, and sturdy work boots; add face shields, hearing protection, high-visibility clothing, and respiratory protection where the hazard assessment requires them. For cement contact, use impervious, waterproof, alkali-resistant gloves, waterproof boots high enough to keep cement out, and long sleeves/long pants. For dust or splash hazards, use safety glasses with side shields, goggles, or face shields as appropriate. PPE must fit properly and should never replace ventilation, guarding, wet methods, or other engineering controls. [3] [8] [11]

Dust and silica exposure control is a critical topic in cement plants. Do not breathe dust. Use enclosed transfer points, local exhaust ventilation, process enclosures, dust collection, and wet methods where feasible to keep airborne contaminants below exposure limits. Avoid dry sweeping and compressed-air cleanup when they create airborne dust; use wet cleanup or HEPA-filtered vacuuming instead. Keep eating and drinking areas free of cement dust, wash hands before breaks, and remove contaminated clothing before entering eating areas. Exposure monitoring should be used to verify controls are effective, especially where silica-containing materials are dumped, conveyed, crushed, ground, or cleaned. [5] [4] [1]

Relevant exposure limits in the provided documents include respirable crystalline silica at 0\.05 mg/m³ OSHA PEL in several product SDSs, with ACGIH TLV listed as 0\.025 mg/m³ respirable. For Portland cement and nuisance dusts, the documents list OSHA PELs such as 5 mg/m³ respirable and 15 mg/m³ total dust for Portland cement or particulates not otherwise regulated. These values reinforce the need for exposure assessment, ventilation, and respiratory protection when controls cannot keep exposures low enough. [6] [4] [9]

For respiratory protection, use respirators only after evaluating the task and confirming that engineering and administrative controls are not enough. Where a risk assessment shows respirators are necessary, use a properly fitted, NIOSH-approved particulate respirator suitable for the exposure. Respirator selection must be based on known or anticipated exposure levels and managed under a compliant respiratory protection program that includes medical evaluation, fit testing, training, maintenance, and supervision by a competent health and safety professional. Workers must be clean-shaven where the facepiece seals and must know the limitations of the respirator they are wearing. [8] [7] [1]

Machine guarding and conveyor/rotating equipment safety must be emphasized in every cement facility. Never operate equipment with missing or ineffective guards. Keep hands, feet, clothing, jewelry, and hair away from nip points, rollers, gears, chains, couplings, and rotating shafts. Do not reach into moving conveyors or attempt to clear jams while equipment is running. Stay out of line-of-fire areas around belts, pulleys, and transfer points, and use designated walkways and barriers around moving equipment. Inspect guards before use and report damaged guarding immediately. [10] [10] [10] [1]

For lockout/tagout, no one may clean, service, adjust, lubricate, unjam, or enter danger zones of conveyors, crushers, mixers, fans, or other powered equipment until all hazardous energy is isolated, locked, tagged, and verified at zero energy. This includes electrical, mechanical, hydraulic, pneumatic, gravity, spring, and stored material energy. Try-start verification and release/blocking of stored energy are essential. Only authorized employees should apply and remove locks, and group LOTO should be used when multiple trades are involved. [10]

For manual handling, plan the lift, reduce load size where possible, use mechanical aids, team lifts, and proper body mechanics. Keep the load close, maintain a straight back, bend the knees, avoid twisting, and do not rush. Rotate high-exertion tasks and warm up before heavy work. Cement bags, hoses, tools, and maintenance parts can all create overexertion risk, especially when handled repeatedly or in awkward spaces. [1] [2]

Housekeeping and traffic management are major incident-prevention controls in cement operations. Keep floors, stairs, platforms, and access routes clear of dust buildup, spills, tools, hoses, and debris. Clean up promptly to prevent slips, trips, and secondary dust exposure. Separate pedestrians and mobile equipment where possible, maintain marked travel lanes, use spotters for restricted-visibility movements, and ensure backup alarms and lights are working. Make eye contact with operators before approaching equipment, and never walk under suspended loads or near moving booms, chutes, or reversing vehicles without communication and clearance. [2] [5] [2] [10]

For emergency procedures, workers should know how to report an emergency, activate alarms, summon medical help, and identify eyewash, clean water, first aid supplies, fire extinguishers, spill materials, and evacuation routes. Cement exposure requires immediate response: flush eyes or skin with clean water promptly, remove contaminated clothing, and seek medical evaluation for persistent irritation, burns, breathing difficulty, or eye exposure. Emergency drills should cover fire, medical events, entanglement, engulfment, and vehicle incidents, with clear rescue roles and no improvised rescue into energized or moving equipment. [3] [8] [2]

Incident prevention depends on disciplined pre-job planning, inspections, training, supervision, and stopping unsafe work. Use pre-task plans, JSAs/JHAs, line-of-fire reviews, guard inspections, dust-control checks, and verification that SDS information is available and understood before chemical exposure tasks begin. Encourage near-miss reporting, correct unsafe conditions immediately, and investigate incidents for root causes rather than blame. Fatigue, shortcuts, poor communication, and bypassing guards are recurring contributors to serious injuries. [1] [10] [10]

For OSHA regulatory compliance, a cement industry safety program should align at minimum with requirements for PPE hazard assessment and use, respiratory protection, machine guarding, control of hazardous energy, walking-working surfaces, hazard communication/SDS access, powered industrial trucks and mobile equipment as applicable, and silica/dust exposure control. The provided documents specifically reference OSHA respiratory protection standard 29 CFR 1910\.134, OSHA concrete and masonry construction resources, and OSHA exposure limits for silica and dust. Compliance should include written programs where required, employee training, exposure assessments, inspections, and documented corrective actions. [7] [1] [6] [11]

Practical close-out message for the crew:

  • Identify the hazards before starting the task and stop if conditions change
  • Use engineering controls first: ventilation, enclosures, wet methods, guarding, barriers, and traffic controls
  • Wear the required PPE correctly every time
  • Never bypass guards or reach into moving equipment
  • Lock out, tag out, and verify zero energy before maintenance or jam clearing
  • Control dust, avoid dry cleanup methods that create airborne silica, and wash up before breaks
  • Use safe lifting methods and ask for help with heavy or awkward loads
  • Report near misses, damaged guards, dust-control failures, and unsafe conditions immediately

# PINCH POINTS Date Posted: 09/02/2016 A Pinch Point is produced when 2 objects come together and there is a possibility that a person could be caught or injured when coming in contact with that area. Pinch points commonly impact fingers/hands, but can impact any area of the body. The injury resulting from a pinch point could be as minor as a blister or as severe as amputation or death. Conveyors, gears, loaders, compactors and other moving equipment are examples of machinery with pinch points. ## COMMON CAUSES OF INJURIES FROM PINCH POINTS • Not paying attention to the location of hands and feet • Walking or working in areas with mobile equipment and fixed structures • Loose clothing, hair or jewelry getting caught in rotating parts or equipment • Poor condition of equipment and guarding - Dropping or carelessly handling materials or suspended loads • Not using the proper work procedures or tools • Reaching into moving equipment and machinery ## SAFETY CONTROLS FOR PINCH POINTS • Verify all guarding is in place and effective • Wear the appropriate personal protective equipment. Gloves, hi-vis clothing and heavy boots. • Identify potential pinch points before starting work by conducting a pre task inspection. • Stay in employee designated areas: Always make sure mobile equipment operators know your location. • Lockout/Tagout: Always verify electrical equipment is de-energized before starting any maintenance work • Alertness: Drowsiness leads to inattentive work habits and shortcuts • Operating manuals and work procedures: Always review the operating instructions/manuals before starting work; pinch points may also be identified in these documents. • Ensure all mobile equipment has working backup alarms and lighting before use. ## QUESTIONS FOR DISCUSSION • What are the most common sources of pinch points in your work area? • What improvements can be made to machine guarding? ## PRESENTER TIPS • Pre-read the Toolbox Talk.

# CONCRETE PLACEMENT Date Posted: 05/12/2025 ## Concrete Placement Concrete is composed of cement, sand, and aggregate, which are a collection of raw materials, like sand, gravel, and crushed stone, that make up a large portion of concrete and water. When these components are mixed in the correct proportions, concrete becomes a stable and versatile building material that can be used for various applications such as roads, bridges, buildings, septic tanks, and even household countertops. The versatility of concrete in building applications can be achieved by adjusting the proportions of air and other variables in the mixture. Additionally, strengthening materials like re-bar, fiberglass strands, and plastic rods are added to reinforce the concrete. According to the Center for Construction Research and Training (CPWR), there were over 3,000 injuries that resulted in days away from work due to concrete pour- related work. Concrete work is often physically demanding and poses many hazards for those working in this field. Although there may be a need for a steady or fast pace at times, it is crucial to take the time to identify the hazards of the work and minimize them. ## HAZARDS OF WORKING WITH CONCRETE - Chemical burns: It is crucial to protect your skin from coming into direct contact with concrete. Dry cement and wet concrete can lead to skin irritation, dermatitis, or even a chemical burn. The chemicals in cement extract moisture from anything to help in the drying process. When cement pulls the moisture from the skin, it damages the skin cells severely. If left untreated, once concrete hardens, the skin will blister, swell, and bleed, resulting in a second to third- degree burn. In the most severe cases, skin contact with concrete has led to scarring, the need for skin grafts, and even amputations. Therefore, it is essential to wear proper PPE such as gloves, boots, and eye protection when working with cement materials like wet concrete. It is frequently r…

Open source document

Source excerpt

# CONCRETE AND MASONRY SAFETY ## Date Posted: 05/29/2024 Concrete is a common building material used regularly in the construction industry. Concrete generally made by combining cement, sand, aggregate (small stones), and water. Some applications of concrete necessitate adding other materials that could adversely affect health if improperly handled or appropriate precautions are not taken. Additions may include alkaline compounds (such as lime) that are corrosive to human tissue. Crystalline silica can be abrasive to the skin and cause lung damage, and small quantities of chromium can cause allergic reactions. According to the Occupational Safety and Health Administration (OSHA), over 250,000 people work i concrete or masonry trades. Over 10 percent of those workers (28,000) experienced a job-related injury or illness, and 42 died in just a year. ## HAZARDS WORKING WITH CONCRETE • Eye, skin, and respiratory tract irritation from exposure to cement dust. • Inadequate safety guards on equipment. • Ergonomic risk (overexertion and awkward postures). - Slips, trips, and falls. • Chemical burns from wet or dry concrete. - Confined spaces • Noise exposure ## DIFFERENT PHASES OF WORKING WITH CONCRETE PRESENT DIFFERENT RISKS Forming risks: Concrete forming is the process of creating solid frames to hold the concrete in place as it sets after being poured. Most concrete projects require forms before you even order or mix the concrete. You need use structurally sound forms to hold the concrete in place and avoid collapse. Risks during this stage include: to • Workers falling during steel fixing (tying rebar) and the erection of formwork. • Collapse of the formwork. • Materials falling during the striking of formwork. • Silica dust exposure. • Manual handling of materials such as formwork, reinforcing bars (rebar), etc. • Skin irritation. Mixing risks: Cement dust released during bag dumping or concrete cutting can irritate the skin. Moisture from sweat …
