Study Notes

Chemical Agents

Criminal justice officers use OC (oleoresin capsicum) or CS (orthochlorobenzal-malononitrile) to control resistant subjects
OC (pepper spray) is an inflammatory agent
Symptoms: tearing, involuntary eye closing, nasal discharge, sneezing, disorientation, respiratory distress, skin redness and puffiness
Effects typically last 20-30 minutes, but may be longer in some cases
CS is an irritant agent
Symptoms: burning/tearing eyes, nasal discharge, skin/upper respiratory irritation, sensation of intense burning (no actual burning)

OC Spray Active Ingredient

Oleoresin capsicum is a natural derivative of cayenne pepper (with some synthetic forms)
Active ingredient: capsaicin
Capsaicin causes the burning sensation when it contacts human tissue

Measuring Burning Effects

Scoville Heat Units (SHU) are used to measure the heat/burning effects of capsicum
SHU scale was originally designed for peppers (restaurant industry)
OC is a vegetable product and not directly comparable to thermal degrees of fire

Chemical Agent Effects on Subjects

OC in eyes: causes eyes to close, intense burning, bloodshot eyes
OC inhaled: coughing, gasping, gagging, vomiting
Affects skin, throat: swelling, sneezing, mucous discharge
Officers should use caution when approaching subjects, for cross-contamination

Prolonged/Severe Reactions to Chemical Agent Contamination

Officers should watch contaminated subject until they recover
Seek medical attention if the person has acute symptoms, maintain open airway, and ensure continuous breathing and circulation.
Use the manufacturer's safety data sheet (SDS)
Observe for unusual behaviors

Canister Maintenance

Canisters are designed to be soft, pliable, and resistant to cracking/splitting
Don't typically need concern about leaking

Decontamination Procedures

Essential for chemical agent use
Decontamination procedures vary by agency
Start decontamination as soon as the subject is under control
Avoid leaving an unattended contaminated person

Psychological Decontamination

Reassure the exposed person that the contaminant is temporary and causes no lasting effects
Guide the person through physical decontamination:
Strobing (forceful blinking) the eyes
Breathing exercises
Removing contaminants from skin
Using water to rinse eyes and skin
Using decontamination solutions (e.g., baby shampoo)
Avoid using oil-based soaps for decontamination

Documentation

Document the use of chemical agents as a use of force, following agency policies
