How long does an acute exposure last?
An acute exposure is defined as an exposure to a chemical for a duration of 14 days or less. Although the duration of exposure during an unscheduled chemical release may be brief, the chemical concentration may be high. The onset of health effects resulting from an acute exposure can be immediate or delayed.
Why are chemical accidents increasing?
Because thousands of chemicals are manufactured, used, and transported in the United States, the number of accidents involving chemical exposures is increasing. Although most of these accidents occur at fixed facilities where the chemical hazards are known, emergency medical personnel are increasingly more likely to be involved in incidents in which victims have been exposed to an unknown or incorrectly identified chemical hazard. Emergency medical technicians, therefore, must learn to deal with presenting symptoms and provide basic supportive medical care for complications (respiratory, cardiovascular, and neurologic) that are most likely to cause a serious threat to life.
What are the potential hazards of secondary contamination?
Potential for Secondary Contamination. The route and extent of exposure are important in determining the potential for secondary contamination. Victims who were exposed to only gas or vapor but have no gross deposition of the material on their clothing or skin are not likely to carry significant amounts of chemical beyond the Hot Zone and are not likely to pose a risk of secondary contamination to other personnel. However, victims whose skin or clothing is soaked with liquid chemical or victims who have condensation of chemical vapor on their clothes or skin may contaminate others by direct contact or by off-gassing vapor. If the victim has ingested a chemical, toxic vomitus may pose a danger to others through direct contact or off-gassing vapor.

What chemicals are used in fires?
Victims trapped near the fire source may be exposed to hot and dense smoke with off-gassing chemicals including carbon monoxide (CO) and cyanide. Often, these chemicals cause bronchospasm, sloughing of the epithelial lining of the airway, mucus secretion, inflammation and surfactant inactivation.
What materials were used in fire smoke?
The homes of our grandparents and great-grandparents were largely furnished with wood, cotton and wool since these were the common materials used in manufacturing in the 1940s and 1950s.
Is CO a chemical?
CO and HCN are both chemical asphyxiates commonly found in fire smoke, and exposure should be considered in every case of smoke inhalation. CO is produced when a carbon-containing material, such as wood, is burned and there isn’t enough oxygen present to completely transform into carbon dioxide (CO 2 ).
What is the purpose of the respiratory protection bulletin?
The intent of this technical bulletin is to summarize and clarify the respiratory protection guidance from both USP and NIOSH for workers who handle hazardous drugs in the healthcare environment.
What is the APF of a respirator?
OSHA Assigned Protection Factor (APF) provides the factor by which a properly fitted and properly used respirator will reduce your exposure. The higher the APF the greater the potential reduction in exposure. Headtops have an APF of 25; hoods have an APF of 1000.
What is the best deactivating agent for bleach?
Sodium Hypochlorite (bleach) and Peracetic acid/peroxide-based cleaners are both strong oxidizers and are listed as appropriate deactivating agents for some hazardous drugs (always check the Safety Data Sheet for the particular hazardous drugs being used in your facility). 3M testing has shown that a particulate respirator will reduce bleach exposures (odor may still come through – if that is a concern then use a combination particulate cartridge with an Acid Gas adsorbing carbon). For peracetic acid/peroxide based cleaners a combination particulate cartridge with Organic Vapor capabilities can be used to help reduce exposures. (3M recommends the OV/AG/Particulate cartridges, which will help reduce respiratory exposures to the hazardous drugs and both of these neutralizing agents).
Why is it important to care for gas and chemicals?
Care in handling gases and chemicals is the most important preventive measure. The availability of adequate respiratory protection (eg, gas masks with a self-contained air supply) for rescuers is also very important; rescuers without protective gear who rush in to extricate a victim often succumb themselves.
What is respiratory damage?
Respiratory damage is related to the concentration and water solubility of the gas and the duration of exposure. More water-soluble gases (eg, chlorine, ammonia, sulfur dioxide, hydrogen chloride) dissolve in the upper airway and immediately cause mucous membrane irritation, which may alert people to the need to escape the exposure.
What are the complications of acute exposure?
Complications of acute exposure may include acute respiratory distress syndrome, bacterial infections, and bronchiolitis obliterans (sometimes leading to pulmonary fibrosis). Diagnosis of acute exposure is usually obvious by history, but do pulse oximetry, chest x-ray, spirometry, and lung volume assessment.

What is irritant gas?
Irritant gases are those which, when inhaled, dissolve in the water of the respiratory tract mucosa and cause an inflammatory response, usually due to the release of acidic or alkaline radicals . Irritant gas exposures predominantly affect the airways, causing tracheitis, bronchitis, and bronchiolitis.
Where can an inhalational injury occur?
Inhalational injury can occur anywhere along the airway passages and can be classified based on the primary area of injury such as upper airway, the tracheobronchial system, or lung parenchyma. Direct visualization of the airways will help confirm diagnosis.
Can smokers recover from lung injury?
Most people recover fully, but some have persistent lung injury with reversible airway obstruction ( reactive airways dysfunction syndrome) or restrictive abnormalities and pulmonary fibrosis; smokers may be at greater risk.
