The original, patented, fully tested OC formulation. Over many years of safe, effective use, First Defense has proven itself as the pepper spray of choice for law-enforcement and corrections the world over.
FIRST DEFENSE® OC Formulation was created to provide the safest OC aerosol on the market. Today it's the most widely used pepper spray in law enforcement and corrections throughout the world. Three out of four police departments choose First Defense® OC Aerosols by Defense Technology—not only for their proven effectiveness, but because they are the only such products backed by a comprehensive effectiveness study, and the only products that address the ever-growing concerns over health and environmental risks.
First Defense® Oleoresin Capsicum is water-soluble. It is processed further than oil-based OC to remove natural oils, waxes and fats; yielding a formulation that is clear of color and consistent in its potency. At 500,000 SHU, it’s also the hottest, water-soluble OC available. Based on their extensive research, Defense Technology has determined that their 0.2% capsaicinoid level is optimum for consistent effectiveness. But because First Defense’s water-soluble OC formula decontaminates more easily then oil-based solutions, it not so excessive that decontamination time or simplicity is compromised.
Aimable stream delivery. The First Defense MK-9 aerosol can deploy a high volume, target-specific stream up to 25 ft*. This allows for controlled delivery of large quantities of OC deterrent with minimal cross contamination. This also provides a safer margin of effective distance with less chance of disturbance by wind or rain compared to alternate delivery system.
Non-flammable, environmentally friendly, simple to clean. First Defense OC Aerosols use only food-grade formulations and safe nitrogen propellant, making them completely non-flammable and biologically sound. They contain no HCFCs or CFCs. And because First Defense is water-soluble, it allows relatively easy clean-up and decontamination of skin and surfaces, using soap and water or just a damp cloth. Clothing and fabrics can be cleaned by machine washing or dry cleaning. Airborne OC can be cleared from buildings with simple ventilation.

SAFE AND EASY TO USE: Each unit has a steel "pull-ring" type safety pin which must be removed to enable the actuator button at the top of the carry handle. The actuator button itself has a break-free locking tab preventing accidental discharge until the first deployment. The absence of this break-free pin also indicates that the unit has been actuated at least once.
INDIVIDUALLY SERIALIZED: Wear and water-resistant labels affixed to all units permit easy identification. Lot numbers for formulation are present for quality assurance tracking.
