First Defense® 1.3% MK-4 Foam OC Aerosol
The MK-4 is an ideal size for patrol officers to wear on a duty belt and will deliver 20-25 short bursts of OC at an effective range of 10-12 ft. This 1.3% MC OC aerosol product utilizes a foam delivery method providing a powerful and fast-acting foam that coats the face upon contact.
Non-flammable / Electronic Discharge Weapon (EDW) safe
- The 1.3% MC red banded canister indicates the major capsaicinoid level which is discharged at the nozzle at time of use.
- The MK-4 is an ideal size for patrol officers to wear on a duty belt.
- This formulation has been tested and is non-flammable and Electronic Discharge Weapon (EDW) safe.
- Defense Technology® First Defense® OC Aerosols are produced in an ISO rated manufacturing facility.
- All Major Capsaicinoid percentages (MC%) are verified by an Independent Laboratory for quality assurance.
STORAGE OF OC PEPPER SPRAY CANISTERS
Poor storage conditions will significantly reduce the shelf life of these products resulting in the replacement of the canisters sooner than necessary or the possible use of defective products. Humidity and heat are the two most damaging factors that destroy OC canisters.
The canisters and grenades should be stored in a controlled atmosphere with temperatures between 60 degrees Fahrenheit to 75 degrees Fahrenheit with less than 60% relative humidity.
Canisters should remain sealed in their shipping containers until they are to be used or placed in a duty belt/holster.
Never store canisters in the trunk of a car for prolonged periods. The heat may cause the canisters to build pressure and eventually release propellant and possibly agent or OC.
Stored munitions should be inspected for physical integrity and a representative sample functioned twice a year. Munitions that have surpassed the warranty of 5 YEARS should be replaced.
DISPOSAL OF OC PEPPER SPRAY CANISTERS
The following information is intended only to provide general information for our customers. It is extremely important that anyone using our products comply with all applicable environmental laws and regulations. We recommend that you consult with appropriate legal counsel or governmental authorities prior to disposing of any of our chemical products.
In 1976, Congress enacted a law entitled, The Resource Conservations and Recovery Act of 1976 (RCRA). This law was intended to protect human health and the environment from imprudent disposal of “hazardous wastes.”
Outdated or otherwise unusable pyrotechnic items are considered “hazardous waste” under RCRA and are assigned the EPA hazardous waste code of D00 1 due to their ignitable characteristic. Disposal of these items must be done in accordance with all applicable Federal and/or State laws. Many states have hazardous waste management programs that are much more stringent than Federal law. For this reason, you should check with the EPA Regional Office to determine to what extent these laws apply to you.
What is the difference between SHUs and MC%?
Defense Technology® no longer recognizes Scoville Heat Units (SHUs) as a viable means to measure pungency in regards to pepper spray.
Scoville Heat Units are a subjective measurement system dating back to the American Spice Trade. For years SHUs have been used as a measuring system within the pepper spray industry, resulting in confusion and a lack of confidence and consistency regarding the pungency and percentage of OC formulations.
High Performance Liquid Chromatography or HPLC, is the only true way to measure the heat of a formulation. It is a scientific method and ensures consistency. This is the standard used by Defense Technology®. The finished Defense Technology® OC formulations are tested at an independent laboratory tested for the exact percentage of major capsaicinoids (MC%).
