Ricin

CAS RN: 9009-86-3

Other Preventive Measures

Decontamination: Casualties/personnel: Remove potentially contaminated clothing. Wash skin with soap and water. Small Areas: Wash all surfaces with undiluted household bleach insuring a minimum contact time of 10 minutes. Wash the area with soap and water followed by rinsing with copious amounts of water. Extreme care must be exercised when dealing with dry or powdered agents as Toxins may adhere to the skin or clothing and present an inhalation hazard later. /Toxins/
DECONTAMINATION CORRIDOR: The following are recommendations to protect the first responders from the release area:
Decontamination Corridor
Position the decontamination corridor upwind and uphill of the hot zone.
The warm zone should include two decontamination corridors. One decontamination corridor is used to enter the warm zone and the other for exiting the warm zone into the cold zone. The decontamination zone for exiting should be upwind and uphill from the zone used to enter.
Decontamination area workers should wear appropriate PPE.
A solution of detergent and water (which should have a pH value of at least 8 but should not exceed a pH value of 10.5) should be available for use in decontamination procedures. Soft brushes should be available to remove contamination from the PPE.
Labeled, durable 6-mil polyethylene bags should be available for disposal of contaminated PPE.
INDIVIDUAL DECONTAMINATION: The following methods can be used to decontaminate an individual:
Decontamination of First Responder
Begin washing PPE of the first responder using soap and water solution and a soft brush. Always move in a downward motion (from head to toe). Make sure to get into all areas, especially folds in the clothing. Wash and rinse (using cold or warm water) until the contaminant is thoroughly removed.
Remove PPE by rolling downward (from head to toe) and avoid pulling PPE off over the head. Remove the SCBA after other PPE has been removed.
Place all PPE in labeled durable 6-mil polyethylene bags.
INDIVIDUAL DECONTAMINATION: The following methods can be used to decontaminate an individual:
Decontamination of Patient/Victim
Remove the patient/victim from the contaminated area and into the decontamination corridor.
Remove all clothing (at least down to their undergarments) and place the clothing in a labeled durable 6-mil polyethylene bag.
Thoroughly wash and rinse (using cold or warm water) the contaminated skin of the patient/victim using a soap and water solution. Be careful not to break the patient/victim's skin during the decontamination process, and cover all open wounds.
Cover the patient/victim to prevent shock and loss of body heat.
Move the patient/victim to an area where emergency medical treatment can be provided.
If you think you may have been exposed to ricin, you should remove your clothing, rapidly wash your entire body with soap and water, and get medical care as quickly as possible.
Removing your clothing: Quickly take off clothing that may have ricin on it. Any clothing that has to be pulled over the head should be cut off the body instead of pulled over the head. If you are helping other people remove their clothing, try to avoid touching any contaminated areas, and remove the clothing as quickly as possible.
Washing yourself: As quickly as possible, wash any ricin from your skin with large amounts of soap and water. Washing with soap and water will help protect people from any chemicals on their bodies. If your eyes are burning or your vision is blurred, rinse your eyes with plain water for 10 to 15 minutes. If you wear contacts, remove them and put them with the contaminated clothing. Do not put the contacts back in your eyes (even if they are not disposable contacts). If you wear eyeglasses, wash them with soap and water. You can put your eyeglasses back on after you wash them.
Disposing of your clothes: After you have washed yourself, place your clothing inside a plastic bag. Avoid touching contaminated areas of the clothing. If you can't avoid touching contaminated areas, or you aren't sure where the contaminated areas are, wear rubber gloves, turn the bag inside out and use it to pick up the clothing, or put the clothing in the bag using tongs, tool handles, sticks, or similar objects. Anything that touches the contaminated clothing should also be placed in the bag. If you wear contacts, put them in the plastic bag, too. Seal the bag, and then seal that bag inside another plastic bag. Disposing of your clothing in this way will help protect you and other people from any chemicals that might be on your clothes. When the local or state health department or emergency personnel arrive, tell them what you did with your clothes. The health department or emergency personnel will arrange for further disposal. Do not handle the plastic bags yourself.
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
