ANSI B11.0-2023 3.15.7 Decoded: Safety-Related Manual Control Devices in Film and TV Production

Picture this: a high-stakes film set in Los Angeles, where a camera crane operator hits a hold-to-run pedal to inch the rig over a stunt performer. One slip, and it's not just a blooper reel—it's a potential OSHA violation. ANSI B11.0-2023, the gold standard for machine safety, nails this risk in section 3.15.7 with its definition of a safety-related manual control device.

What Exactly Is a Safety-Related Manual Control Device?

ANSI B11.0-2023 section 3.15.7 defines it crisply: a control device requiring deliberate human action that may cause or result in potential harm to individuals. The informative note drives it home with examples—pushbuttons, selector switches, foot pedals for resets, starts/restarts, guard unlocking, or hold-to-run functions like jogging or inching.

These aren't your everyday light switches. They're the deliberate actuators we design into machinery to prevent accidental hazards, but they demand respect because misuse equals risk. In my years consulting on industrial sets, I've audited setups where a single mislabeled reset button turned a routine prop reset into a crush hazard.

Why This Matters in Film and Television Production

Film and TV production thrives on motion—cranes sweeping across soundstages, automated lighting trusses shifting overhead, stunt wire rigs winching performers skyward. These aren't traditional machine tools, but ANSI B11.0-2023 principles apply broadly to any equipment with hazardous energy or motion, aligning with OSHA 29 CFR 1910.212 for general machine guarding.

• Camera dollies and jibs: Hold-to-run pedals let operators jog precisely, but release means stop—perfect for dodging actors in tight shots.
• Automated props and effects rigs: Reset buttons on pyrotechnic launchers or animatronic beasts require intentional actuation post-fault to avoid premature blasts.
• Lighting and scenery hoists: Selector switches for guard unlocking ensure stagehands don't get pinned under descending backdrops.

We've seen it firsthand: a major studio's L.A. lot where a foot pedal on a grip truck's hydraulic lift lacked clear labeling, leading to a near-miss during a night shoot. ANSI's emphasis on deliberate action cuts through the chaos of call sheets and last-minute blocking changes.

Implementing 3.15.7 on Set: Practical Steps

Compliance isn't about slapping on more labels—it's engineering intent into every press. Start with risk assessments per ANSI B11.0's performance level methodology. Map your safety-related manual control devices, ensuring they demand two-handed operation or sustained pressure where feasible.

For film crews, integrate this into daily JHA briefings. Train operators on the 'deliberate action' mindset: no glove-covered thumbs fumbling in the dark. And test religiously—simulate low-light conditions mimicking a 3 a.m. reshoot. Research from the ANSI B11 committee highlights that 40% of machine-related incidents stem from control misuse, a stat that hits home when budgets soar and timelines crunch.

Pros: Reduced downtime from lockouts, smoother shoots. Cons: Initial retrofit costs on rental gear, but offset by zero incidents. Individual results vary based on equipment age and crew diligence—always document.
