I follow manufacturer guidelines and develop my own checklist for regular inspection and preventative maintenance, which includes cleaning, lubricating moving parts, and tightening bolts. This helps extend the lifespan of the equipment and prevent unexpected failures on set.

Efficient inventory management is crucial. I use a combination of a physical inventory log and a digital database to keep track of parts and supplies. The physical log allows for quick visual checks of available items. The digital database provides a detailed record of each part, including its quantity, condition, purchase date, and location. This system allows for easy tracking of stock levels, ordering replacements, and identifying potential shortages.

For example, I use a spreadsheet where each column represents a different grip accessory, and each row records the quantity of each part, the part’s number, and when it was last used. When a part is used or a new one is acquired, it’s instantly recorded into the spreadsheet. This helps to minimize downtime and reduce the risk of unexpected shortages during productions.

Unexpected equipment failure requires quick thinking and problem-solving. My approach involves a series of steps: first, assess the situation – what exactly failed, and what’s the impact on production? Then, I explore immediate solutions – can I quickly repair it using readily available tools and parts? If not, I brainstorm alternative solutions—can I substitute the failed piece with a similar item? Can I adjust the setup to work around the failure?

For example, if a light stand collapses, my first reaction is to check for injuries and secure the area. Then, I assess the damage and try to find a quick fix, such as using another stand. If that’s not feasible, I’ll consult with the gaffer to find an alternative lighting solution that minimizes disruption to the shoot. Effective communication and resourcefulness are vital in these unexpected scenarios. The goal is always to find a workable solution as quickly and efficiently as possible.
