Throughout my career in the security industry, I've learned various types of gear and equipment to carry on me. Early on, I thought I needed anything and everything for my every day carry (EDC). Nowadays, I only carry tools on me that I will actually use. To start, the most important tool is a quality flashlight. I consider anything 200 lumens or better, as a quality light. My light of choice is a 750 lumen, Streamlight ProTac HL. I use to carry a 200 lumen Streamlight TL-2X, but needed to upgrade my lumens due to the venue I work in. Being able to illuminate an area in the venue, not only is great for general visibility, it aids in signaling coworkers you need help. A flashlight is also a simple mental judo technique to let guests know you are there, and you can see them. Next would be a basic medical kit. I personally carry two kits on me. One for basic cuts, and bleeding, and one for trauma care. My basic first aid kit contains band-aids, alcohol swabs, gauze pads, and gloves.
I also carry an IPAK (Individual Protective Agent’s Kit, also know as an IFAK, Individual First Aid Kit) for emergency trauma care. The IPAK contains QuikClot gauze, SWAT-T tourniquet/pressure bandage, a CPR face shield, antiseptic wipes, and gloves. Before you start carrying first aid kits, for your safety, and others, make sure you are trained & certified in first aid. Local health departments, or American Red Cross locations, offer inexpensive/free courses. Depending on the size of your venue, I highly recommend a decent radio for communication with other staff members. It doesn't have to be anything crazy expensive, or complex. A simple $30 radio, with a noise reduction headset ($20+), is a great investment in yourself & team. I carry a Baofeng radio, Retevis headset, and a SureFire Sonic Defender earpiece attachment for noise cancellation. I also carry a Gerber Crucial multi tool, for various reasons. Minor repairs around the venue are always discovered after you start the shift. If you have time, it's never a bad idea to fix whatever may be broken. Paper towel jams,
