Healthcare providers should use personal protective equipment if there could be a dermal exposure.

2) HOSPITAL: DERMAL EXPOSURE: Remove clothes and wash the skin with water.Activated charcoal binds poorly to cyanide salts however, the lethal dose is so small that the use of activated charcoal should be considered in a patient that presents within one hour of an oral ingestion. 1) PREHOSPITAL: In symptomatic patients, institute emergency measures including basic life support and administration of cyanide antidote kit (if readily available) before performing the following steps.Administer sodium bicarbonate for severe acidemia. In addition, standard ACLS or PALS therapy should be provided to manage symptoms. Patients who are comatose or severely ill due to suspected cyanide poisoning should be administered a cyanide antidote kit. 1) Elevated lactate, increased anion gap metabolic acidosis, and an elevated venous oxygen saturation all suggest a significant cyanide exposure.Worsening or severe acidosis, hypotension, seizures, dysrhythmias and coma indicate a more severe poisoning. An antidote kit should available at the bedside. Establish intravenous access immediately. Supplemental oxygen should be administered immediately with continuous monitoring of vital signs. 1) Patients with even brief or small exposures should be monitored extremely closely for signs of deterioration.

A) MANAGEMENT OF MILD TO MODERATE TOXICITY.Level D for hospital personnel includes scrubs, safety glasses, shoe covers, and possibly a face shield. Level D protective clothing is utilized when there are no respiratory hazard and no major skin hazard considerations.The SCBA is replaced with an Air Purifying Respirator. Level C is similar to B with the exception of the type of respiratory protection.A young soldier can last about 2 hours on a hot day with an external air hose. Level Bs are chemical resistant suits that are designed for splashes of liquids but not for gas or vapor hazards. Level B - requires the use of SCBA but has lesser skin protection.Level A includes a Self Contained Breathing Apparatus (SCBA) with a fully encapsulating vapor tight suit with gloves and booties attached to the suit (tanks last from 1/2 hour to 1 hour). Level A - protective clothing is the highest level of protection.Skin Protection: Chemical-protective clothing is recommended because both hydrogen cyanide vapor and liquid can be absorbed through the skin to produce systemic toxicity. Respiratory Protection: Positive-pressure, self-contained breathing apparatus (SCBA) is recommended in response situations that involve exposure to potentially unsafe levels of hydrogen cyanide. Avoid dermal contact with cyanide-contaminated victims or with gastric contents of victims who may have ingested cyanide-containing materials. Victims whose clothing or skin is contaminated with hydrogen cyanide liquid or solution can secondarily contaminate response personnel by direct contact or through off-gassing vapor.

Victims exposed only to hydrogen cyanide gas do not pose secondary contamination risks to rescuers, but do not attempt resuscitation without a barrier. Hydrogen cyanide is a highly toxic systemic poison that is absorbed well by inhalation and through the skin.
