- Keep the spine in its natural S-shaped curve while sitting or standing to minimize stress on the back and neck
- Avoid slouching, hunching, or leaning forward excessively when operating cameras, control panels, or editing workstations
- Engage core muscles to support the spine and maintain an upright posture throughout the workday
Adjusting chair height and armrests
- Set the chair height so that feet are flat on the floor and knees are at a 90-degree angle to promote proper lower body alignment
- Adjust armrests to support the elbows and forearms while keeping shoulders relaxed and down
- Ensure the chair provides adequate lumbar support to maintain the natural curvature of the lower back
Positioning monitors at eye level
- Place computer monitors or viewfinders at or slightly below eye level to prevent neck strain from looking up or down
- Keep the monitor about an arm's length away to reduce eye strain and maintain a comfortable viewing distance
- Tilt the monitor slightly upward (10-20 degrees) to align with the natural gaze and minimize glare
Safe lifting techniques
Assessing weight and size of objects
- Evaluate the weight and dimensions of equipment, props, or set pieces before attempting to lift them
- Use assistive devices like dollies, carts, or hoists for heavy or bulky items to reduce manual lifting
- Break down larger loads into smaller, more manageable parts when possible
Keeping loads close to body
- Hold objects close to the body, near the waist level, to maintain balance and stability during lifts
- Avoid reaching out or extending arms fully when lifting, as this puts additional strain on the back and shoulders
- Use a wide stance and keep elbows close to the body to engage core muscles and maintain control
Lifting with legs vs back
- Bend at the knees and hips, not the waist, to lift objects from the ground or low surfaces
- Engage leg and core muscles to power the lift, rather than relying solely on back muscles
- Keep the back straight and avoid twisting or jerking motions while lifting to prevent injury
Preventing repetitive strain injuries
Varying tasks and positions
- Alternate between different tasks or workstations throughout the day to avoid prolonged repetitive motions
- Rotate roles among team members to distribute physical demands and prevent overuse of specific muscle groups
- Incorporate standing or walking breaks into sedentary work to promote circulation and reduce static postures
Taking frequent micro-breaks
- Take short breaks (30 seconds to 2 minutes) every 20-30 minutes to stretch, rest eyes, and relax muscles
- Perform simple exercises like shoulder rolls, neck rotations, or wrist stretches during micro-breaks
- Use break reminder software or timers to ensure consistent breaks throughout the workday
Stretching and strengthening exercises
- Engage in regular stretching routines to improve flexibility and reduce muscle tension (shoulder blade squeezes, chest openers)
- Perform targeted strengthening exercises to build endurance in key muscle groups (core, upper back, forearms)
- Consult with a physical therapist or ergonomics specialist to develop a personalized exercise program
Reducing slip, trip and fall hazards
Maintaining clear pathways
- Keep walkways, aisles, and emergency exits free of obstacles, clutter, and debris
- Organize equipment, props, and set pieces in designated storage areas when not in use
- Establish and enforce housekeeping protocols to ensure consistent maintenance of clear pathways
Securing cords and cables
- Use cable covers, ramps, or tape to secure cords and cables that cross walkways or high-traffic areas
- Route cables along walls or overhead whenever possible to minimize tripping hazards
- Implement color-coding or labeling systems for easy identification and organization of cords and cables
Cleaning up spills promptly
- Address spills of liquids, oils, or other substances immediately to prevent slips and falls
- Provide easily accessible spill kits containing absorbent materials, safety cones, and warning signs
- Train staff on proper spill response procedures and emphasize the importance of timely cleanup
Proper use of personal protective equipment
When to wear hard hats and safety glasses
- Wear hard hats when working in areas with overhead hazards (rigging, set construction)
- Use safety glasses when handling chemicals, operating power tools, or in environments with flying debris
- Ensure hard hats and safety glasses meet industry standards (ANSI Z89.1, ANSI Z87.1) and are in good condition
Importance of hearing protection
- Use earplugs or earmuffs in high-noise environments (live music performances, special effects, heavy machinery)
- Monitor noise levels regularly and provide appropriate hearing protection based on exposure duration and intensity
- Educate staff on the long-term effects of noise-induced hearing loss and the benefits of consistent hearing protection use
Selecting appropriate gloves for tasks
- Choose gloves based on the specific hazards of the task (chemical resistance, cut protection, heat insulation)
- Ensure gloves fit properly and allow for adequate dexterity and grip to prevent accidents
- Replace gloves when they show signs of wear, damage, or contamination to maintain their protective properties
Ergonomic equipment design considerations
Adjustability of workstations
- Invest in workstations with adjustable height surfaces to accommodate a range of user sizes and preferences
- Provide adjustable monitor arms, keyboard trays, and seating to allow for customized positioning
- Ensure adjustability features are easy to use and maintain to encourage regular use by staff
Lightweight and portable options
- Select equipment that is lightweight and easy to transport to reduce physical strain during setup and breakdown
- Use modular or collapsible equipment when possible to facilitate storage and minimize handling demands
- Invest in ergonomically designed equipment (cameras, tripods) with features like padded grips and balanced weight distribution
Reducing awkward reaches and twisting
- Arrange workstations to keep frequently used items within easy reach to minimize extended reaches and twisting
- Use swivel chairs or turntables for tasks that require frequent rotation to reduce twisting of the spine
- Implement equipment layouts that promote neutral body positions and minimize awkward postures
Creating a culture of safety
Encouraging early reporting of discomfort
- Foster an open and supportive environment where staff feel comfortable reporting pain, discomfort, or potential hazards
- Provide multiple channels for reporting (in-person, email, anonymous suggestions) to accommodate individual preferences
- Respond promptly and constructively to reports, demonstrating a commitment to addressing concerns and implementing solutions
Providing ergonomics training for staff
- Offer regular sessions to educate staff on proper posture, lifting techniques, and workstation setup
- Include hands-on demonstrations and practice opportunities to reinforce learning and build muscle memory
- Incorporate ergonomics training into new employee onboarding and provide refresher courses for existing staff
Conducting regular safety assessments
- Perform periodic ergonomic assessments of workstations, equipment, and work practices to identify areas for improvement
- Involve staff in the assessment process to gain insights into their experiences and gather suggestions for enhancements
- Use assessment findings to prioritize and implement ergonomic interventions, tracking progress and effectiveness over time
