Striking

A safety warning called on set when heavy equipment moves through the crew area, alerting everyone to clear the path.

Striking

exclamation / verb | Production

A verbal safety warning called out by a grip, electric, or other crew member when they are about to move a large, heavy, or unwieldy piece of equipment through a crowded set area. "Striking" alerts everyone in the vicinity that heavy equipment is in motion and that they should step clear if they are in the path. The call is a standard safety protocol derived from theatre, where "striking" historically referred to dismantling or removing set elements. On film sets, the term has expanded to cover any significant equipment movement through the crew area, as well as the end-of-day disassembly process.

The Explanation: How & Why

Film sets are dense, busy environments. At any given moment, crew members may be looking through viewfinders, watching monitors, adjusting equipment, reading scripts, or engaged in conversation. They are not watching the path behind them or to their sides. A grip moving a 20-pound C-stand with a 4x4 flag attached, or carrying an ARRI L7-C LED fixture through a narrow space between crew and set, represents a genuine hazard to anyone who steps into their path unexpectedly.

"Striking" is the audible alert that clears the social and physical path for that movement. When someone calls "Striking," nearby crew know to step clear if they are in the way. The call does not require everyone to stop what they are doing. It broadcasts a spatial awareness alert that integrates into the set's ongoing activity without halting it.

The term carries multiple meanings on a film set, all sharing the same etymological root. In theatre, "to strike" means to remove or dismantle. On a film set, "striking" can mean: (1) the safety call when moving equipment through the crew area, (2) the process of dismantling the set and packing equipment at wrap ("We are striking the set"), and (3) turning on an HMI or arc lamp ("Striking the light!" warns crew not to look directly at the bulb). Context always distinguishes which meaning is intended. During shooting, "Striking!" is a safety call for a specific movement. At wrap, "striking the set" is the entire end-of-day disassembly. When lighting, "striking" warns of imminent bright light.

The culture of set safety awareness extends beyond "striking." Calls like "Crossing" (moving in front of the camera), "Hot points" (sharp equipment ends), "Watch your head" (overhead equipment), and "Flying in" (something is being tossed) form the communication infrastructure that keeps a set with heavy equipment, cables, stands, and many people working in close proximity safe. When communication breaks down, preventable accidents happen.


Historical Context & Origin

The vocabulary of "striking" on film sets derives directly from theatre production, where "striking" has centuries of history as the term for removing set elements. The theatre's influence on film production vocabulary is pervasive: blocking, strike, wings, upstage, and downstage all come from the theatrical tradition. As film production developed its own professional culture through the studio era, it retained theatrical vocabulary where it remained useful and added film-specific terms where new concepts required new language. "Striking" as both a safety call and a wrap activity is one of the most directly inherited theatrical terms in professional film vocabulary. The additional meaning of "striking a light" (turning on an HMI or arc lamp) is film-specific, originating from the electrical arc that early carbon arc lights produced when ignited.


How It's Used in Practice

Scenario 1 - Light Stand Movement (Grip): A grip needs to move a 12-foot combo stand with a 4x4 flag from camera-left to camera-right during a lighting setup. The stand is tall, heavy, and awkward to carry in a crowded space. They call "Striking!" loudly as they begin moving, repeating it as they approach the camera cart area where 6 crew members are clustered. Crew members shift aside without looking up from their work. The grip moves through without incident. The entire exchange takes 8 seconds.

Scenario 2 - Wrap Process (Gaffer / Grip Department): The director calls the final "Cut" of the day. The 1st AD calls wrap. The grip and electric departments immediately begin striking the set: disassembling stands, coiling 100-foot runs of 4/0 cable, packing ARRI SkyPanel S60 fixtures into road cases. The entire area fills with equipment movement, and "Striking!" calls overlap from multiple crew members simultaneously. The 1st AD and department heads sequence the strikes to avoid creating hazardous congestion. A typical wrap strike takes 45 to 90 minutes depending on setup complexity.

Scenario 3 - Narrow Space Navigation (Key Grip): A location shoot is in a 4-foot-wide corridor. A key grip needs to move a Chapman Hybrid dolly section through the corridor where camera, sound, and continuity are all working. They call "Striking, dolly through" over radio and verbally as they enter the corridor. Crew press to the walls. The dolly section passes through. Work resumes. The clear communication prevented what would otherwise have been a disruptive and potentially hazardous squeeze through an occupied space.


Usage Examples in Sentences

"Striking!" The grip navigates the heavy combo stand past the camera cart without breaking anyone's concentration.

"When we wrap tonight, every department strikes simultaneously. It will be crowded, so keep calling it."

"If you are moving anything bigger than a milk crate through a crowded area, call 'Striking.' That is the rule."

"Striking the 18K on radio. Do not look at the light for the next 10 seconds."


Common Confusions & Misuse

Striking (safety call) vs. Striking (lighting): "Striking" means both the safety call for moving equipment and the warning before turning on an HMI or arc lamp. "Striking the 18K!" means the lamp is about to ignite and crew should not look directly at it. "Striking!" with no object means heavy equipment is moving through the area. Context and the presence or absence of an object (the light, the stand, the dolly) distinguish the two. Crew new to set sometimes confuse these and call "Striking" when they mean "Watch your head" or vice versa.

Striking vs. Hot Points: "Hot points" (or "Points!") is a safety call specifically for equipment with sharp or protruding ends: a flag arm extending from a stand, a boom pole, a C-stand riser at face height. It is a more specific warning than "Striking" and indicates a particular physical hazard rather than general large-equipment movement. Both calls may be used in sequence: "Striking, hot points on the flag arm."


Variations by Context

ContextHow "Striking" Varies
US Film Sets"Striking!" is the standard call for equipment movement. "Striking the set" at wrap means full disassembly. "Striking" a light warns of HMI ignition.
UK Film Sets"Striking" is understood but less commonly used. UK crews more often say "Coming through" or "Watch your back" for equipment movement. "Strike" at wrap is used identically.
Theatre"Striking" refers exclusively to removing set elements or props from the stage. The safety-call usage for equipment movement is a film-set adaptation.
Live Broadcast"Striking" is less common on live broadcast sets, where crew movement is more tightly choreographed and pre-planned. The call is used primarily during setup and strike, not during live operation.

Key People & Films

No specific filmmakers are associated with the term "striking" as it is a crew-level safety protocol rather than a creative technique. However, the IATSE (International Alliance of Theatrical Stage Employees) and its local chapters (Local 728 for set lighting, Local 80 for grips) maintain safety training programs that codify the use of "striking" and other set safety calls. The Contract Services Administration Trust Fund (CSATF) provides mandatory safety training for IATSE members in Los Angeles, including equipment handling and set communication protocols. Productions that fail to enforce safety call discipline face OSHA citations and union grievances.


Equipment / Tools Reference

Equipment most commonly associated with "striking" calls includes ARRI SkyPanel S60 and L7-C LED fixtures (30 to 75 pounds with stands), Matthews 12-foot combo stands with 4x4 flags, Chapman Hybrid and Pee Wee dollies (60 to 120 pounds per section), 4/0 feeder cable (0.5 pounds per foot), and American overhead frames (12x12 and 20x20 silk or solid). HMI fixtures requiring "striking" warnings include the ARRI M40 (4,000W) and M90 (9,000W), which produce intense light on ignition.


Standards & Specifications

Set safety calls including "striking" fall under OSHA general industry standards (29 CFR 1910), which require employers to provide a workplace free from recognized hazards. IATSE safety bulletins specifically address equipment handling and set communication. The CSATF Safety Pass program requires completion of safety training courses before dispatch on union productions in Los Angeles. Production safety manuals distributed by major studios (Disney, Netflix, Warner Bros.) include "striking" in their required set communication vocabulary. Failure to use safety calls can result in OSHA fines, insurance claim denials, and union safety grievances.


Common Questions / FAQ

Q: What does "striking" mean on a film set?

"Striking" has three meanings on a film set: (1) a safety call when moving heavy equipment through a crowded area, (2) the process of dismantling the set at the end of the day or production, and (3) a warning before turning on an HMI or arc lamp. Context and the presence of an object (the light, the stand, the set) distinguish which meaning is intended.

Q: What is the difference between "striking" and "crossing"?

"Striking" is called when moving heavy equipment through the crew area. "Crossing" is called when a person walks in front of the camera during a non-rolling period. Both are set communication calls, but "striking" warns about equipment in motion while "crossing" warns about a person entering the camera's eyeline.

Q: Is "striking" used on non-union sets?

Yes, though enforcement varies. Non-union productions may not have formal safety training programs, but experienced crew members carry the vocabulary from union productions. The absence of safety call discipline on non-union sets is a common indicator of an inexperienced or under-resourced production.


  • Crossing - A related safety and courtesy call for moving in front of the camera; shares the purpose of announcing movement in a crowded set environment
  • Copy That - The radio acknowledgment that confirms a "Striking" call on radio was received
  • Gaffer - The lighting department head whose electric crew frequently calls "Striking" when moving heavy fixtures
  • Grip - The department whose members most frequently call "Striking" when moving stands, frames, and rigging equipment
  • Wrap - The end-of-day activity that constitutes the largest and most sustained "striking" operation of any shooting day

The Shot List Generator is relevant to striking workflow: each setup change on the shot list triggers a striking and repositioning of equipment. A well-organized shot list that groups setups by location and lighting configuration minimizes the volume of striking required between setups.
