Abstract
BACKGROUND Hazardous material (HAZMAT) transportation drivers are responsible for safe delivery of consignments and face multiple challenges carrying out their duties. Drivers are also the first to respond to emergencies and accidents. OBJECTIVES The purpose of the present study was to identify the essential competencies needed by HAZMAT transportation drivers to deal with emergencies. METHODS Three rounds of focus groups were conducted using expert panels comprised of HAZMAT specialists, health, safety and emergency representatives, security experts and transportation advisors from June to July 2019. The panel discussed competencies, gathered from a literature review, for emergency responders. RESULTS The panel identified six (6) core and 23 sub-competencies of HAZMAT drivers. This is the first study in low- and middle-income countries (LMIC) to identify core competencies of HAZMAT truck drivers. CONCLUSIONS The integration of these competencies into a development and training program for drivers will better enable drivers to handle emergencies in an efficient and effective manner. PARTICIPANT CONSENT Obtained. ETHICS APPROVAL The Graduate Advisory Committee of Comsats University approved study protocols. PARTICIPANT CONSENT Obtained. COMPETING INTERESTS The authors declare no competing financial interests.

Abstract
Data from a large, multi-state surveillance system on acute chemical releases were analyzed to describe the type of events that are potentially affecting vulnerable populations (children, elderly and hospitalized patients) in order to better prevent and plan for these types of incidents in the future. During 2003-2005, there were 231 events where vulnerable populations were within ¼ mile of the event and the area of impact was greater than 200 feet from the facility/point of release. Most events occurred on a weekday during times when day care centers or schools were likely to be in session. Equipment failure and human error caused a majority of the releases. Agencies involved in preparing for and responding to chemical emergencies should work with hospitals, nursing homes, day care centers, and schools to develop policies and procedures for initiating appropriate protective measures and managing the medical needs of patients. Chemical emergency response drills should involve the entire community to protect those that may be more susceptible to harm.

Abstract
Data from the Hazardous Substances Emergency Events Surveillance system was used to identify factors associated with the severity of injuries of victims (an ordinal outcome variable) harmed in acute chemical release events in the manufacturing industry. We used proportional odds models to account for the order of severity in the outcome, with the general estimation equation. There were 659 events involving 2826 victims. More severe injuries were associated with explosion (adjusted OR aOR = 6.45), multiple chemicals (aOR = 1.75), multiple chemical categories (aOR = 1.70), the chemical group acids (aOR = 1.6), multiple injuries to an individual (aOR = 1.38-1.56) (ranges represent several models), confinement within a structure in a fixed facility (aOR = 1.76-1.90), and being located in the midwest region (aOR = 1.76-1.90). The summer was less likely than all other seasons to be associated with more severe outcome. The results provide information beneficial for preventive activities.

Abstract
Unplanned releases of ammonia lead more often to evacuation and injury than releases of other chemicals, but few studies have systematically investigated ammonia releases. We analyzed Hazardous Substances Emergency Events Surveillance system data for 1993-1998. Evacuation of a total of at least 40,680 persons resulted from 537 ammonia releases, and 248 ammonia releases led to injury of 1434 persons. Equipment failure and operator error were cited as factors contributing to ammonia releases 90% of the time. Eighty-seven percent of releases occurred at fixed facilities. Risk factors for evacuation and injury differed between the food-manufacturing industry and other industries. Indoor release was a consistent risk factor, whereas quantity of ammonia released was not always a risk factor. Preventive maintenance and worker training may be effective tools to reduce the burdens of hazardous ammonia releases.

Abstract
INTRODUCTION On 18 July 2001, a train hauling hazardous materials, including hydrochloric acid, hydrofluoric acid, and acetic acid, derailed in the city of Baltimore, Maryland, resulting in a fire that burned under a downtown street for five days. Firefighters were stymied in their efforts to extinguish the fire, and the city was subjected to thick smoke for several days. OBJECTIVES To determine whether an urban chemical fire with a hazardous materials spill resulted in a detectable public health impact, and to demographically describe the at-risk population for potential smoke and chemical exposure. METHODS The United States Centers for Disease Control and Prevention (CDC) was consulted about possible side effects from chemical exposure. Total numbers of emergency department (ED) patients and admissions from 15:00 hours (h), 15 July 2001 to 15:00 h, 21 July 2001 were collected from five local hospitals. Patient encounters citing specified chief complaints from 15:00 h, 15 July to 15:00 h, 18 July (pre-accident) were compared with the period from 15:00 h, July 18 to 15:00 h, 21 July (post-accident). Data were analyzed using Fisher's exact test. The United States Census Bureau's Topologically Integrated Geographic Encoding and Referencing (TIGER) digital database of geographic features and ArcView Geographic Information Systems (GIS) were used to create maps of Baltimore and to identify populations at-risk using attribute census data. RESULTS There were 62,808 people residing in the immediate, affected area. The mean of the values for age was 33.7 +/- 3.2 years (standard deviation; range = 16 yrs) with 49% (30,927) males and 51% (31,881) females. A total of 2,922 ED patient encounters were screened. Chief complaints included shortness of breath, pre-event = 109 vs. post-event = 148; chest complaints = 90 vs. 113; burns and/or skin irritation = 45 vs. 42; eye irritation 26 vs. 34; throat irritation = 33 vs. 27; and smoke exposure = 0 vs. 15. There was a statistically significant increase (p < 0.05) for shortness of breath and smoke exposure-related complaints. No statistically significant increase in numbers of admitted patients with these complaints was found. CONCLUSIONS In the setting of a large-scale urban chemical fire, local EDs can expect a significant increase in the number of patients presenting to EDs with shortness of breath and/or smoke inhalation. Most do not require in-patient hospitalization. Careful assessment of impact on local EDs should be considered in future city-accident planning. Some official warnings were widely misinterpreted or ignored. Public education on potential hazards and disaster preparedness targeted to populations at-risk should receive a high priority. Geographic information systems (GIS) may serve as useful tools for identifying demographics of populations at-risk for disaster planning and responses.

Abstract
The United States is under the constant threat of a mass casualty cyanide disaster from industrial accidents, hazardous material transportation incidents, and deliberate terrorist attacks. The current readiness for cyanide disaster by the emergency medical system in the United States is abysmal. We, as a nation, are simply not prepared for a significant cyanide-related event. The standard of care for cyanide intoxication is the cyanide antidote kit, which is based on the use of nitrites to induce methemoglobinemia. This kit is both expensive and ill suited for out-of-hospital use. It also has its own inherent toxicity that prevents rapid administration. Furthermore, our hospitals frequently fail to stock this life-saving antidote or decline to stock more than one. Hydroxocobalamin is well recognized as an efficacious, safe, and easily administered cyanide antidote. Because of its extremely low adverse effect profile, it is ideal for out-of-hospital use in suspected cyanide intoxication. To effectively prepare for a cyanide disaster, the United States must investigate, adopt, manufacture, and stockpile hydroxocobalamin to prevent needless morbidity and mortality.

Abstract
The study objective was to analyze hazardous materials event and victim factors associated with transportation of victims to a health care facility, and evacuation or shelter-in-place of nearby populations. A retrospective review was conducted on hazardous materials events in Washington State from 1993 to 1997. Bivariate and multiple logistic regression were used to identify risk factors for transportation, evacuation, and shelter-in-place. Over five years, 2,654 victims from 457 events were reported, with 1,859 (70%) transported to a health care facility. Evacuation occurred in 279 (61%) events and shelter-in-place in 14 (3%) events. After excluding 14 deaths, regression analysis indicated that victims with trauma (OR 5.87, 95% CI 1.41-24.5), thermal burns (6.90, 1.15-41.3), dizziness/other CNS symptoms (1.59, 1.00-2.54), and headache (1.54, 1.01-2.35) were most likely to be transported. Chemical releases inside buildings (2.09, 1.06-4.10, compared with transportation events), and involving 3-5 victims (2.86, 1.54-5.31, compared to 1 victim) or > or =6 victims (8.74, 4.01-19.0), were most likely to involve evacuation or shelter-in-place. Events involving sulfuric acid (0.15, 0.05-0.49) and sodium hydroxide (0.19, 0.04-0.94) were least likely to involve evacuation or shelter-in-place. Prehospital decisions to transport victims to a health care facility and evacuate or shelter-in-place nearby populations are associated with event and victim factors. Further research is needed to determine if these factors also predict need for medical care or removal from exposure, and to develop evidence-based prehospital care protocols for hazardous materials exposure victims.

Abstract
OBJECTIVES To evaluate possible health effects related to work with hazardous materials as measured by end organ effect markers in a large cohort over about 2 years, and in a subcohort over 5 years. METHODS Hepatic, renal, and haematological variables were analysed from 1996-98 in hazardous materials firefighters including 288 hazardous materials technicians (81%) and 68 support workers (19%). The same end organ effect markers in a subcohort of the technicians were also analysed (n=35) from 1993-98. Support workers were considered as controls because they are also firefighters, but had a low potential exposure to hazardous materials. RESULTS During the study period, no serious injuries or exposures were reported. For the end organ effect markers studied, no significant differences were found between technicians and support workers at either year 1 or year 3. After adjustment for a change in laboratory, no significant longitudinal changes were found within groups for any of the markers except for creatinine which decreased for both technicians (p<0.001) and controls (p<0.01). CONCLUSIONS Health effects related to work are infrequent among hazardous materials technicians. Haematological, hepatic, and renal testing is not required on an annual basis and has limited use in detecting health effects in hazardous materials technicians.

Abstract
This analysis describes the frequency and type of injuries among responders to hazardous materials releases. Data were analyzed from states that participated in the Hazardous Substances Emergency Events Surveillance system maintained by the Agency for Toxic Substances and Disease Registry from 1996 through 1998. A total of 348 responders were injured in 126 (0.7%) of 16,986 reported events. Firefighters and police officers were most often injured. Respiratory irritation and nausea were the most commonly reported injuries, and no injuries resulted in death. Almost half of the responder victims wore firefighter turn-out gear, and about a third had received hazardous materials training. Chemicals frequently released during these events were in the category "other substances not otherwise specified" and "acids." Training, education, planning, and coordination are needed to effectively respond to hazardous substances emergency events.

Abstract
The authors carried out a descriptive analysis of acute chemical intoxication in a large petrochemical corporation with 38,000 employees, located in a suburban district of Shanghai, China, to determine the chemicals involved and the primary causes of the incidents. Between 1977 and 1997, 350 cases of acute chemical-intoxication were recorded, resulting in a total of 541 workers with symptoms. Of these, 483 were male and 58, female, with over half the victims under 30 years old. Two hundred and seventy-five cases were serious enough to necessitate hospital admission. There were 266 cases of chemical irritation or inhalation responses (49.2%), 215 cases of mild chemical poisoning (39.7%), 31 cases of moderate poisoning (5.7%), and 29 cases resulting in critical injury (5.4%), including eight deaths (1.5%). The main causes of injury reported by patients were lack of training about safety (63%) and equipment failure (23%). The chemicals involved were asphyxiating gases (302 cases; 55.8%), irritating gases (111 cases; 20.5%), and other toxins. Intervention strategies for the prevention of acute chemical exposures were suggested to the corporation.

Abstract
STUDY OBJECTIVE To describe exposures that prehospital and ED personnel may encounter as a result of hazardous material incidents. METHODS Retrospective analysis of hazardous material incident reports from six district hazardous material teams in Massachusetts from their inception through May 1996. RESULTS The chemicals most frequently involved were various hydrocarbons and corrosive materials. Chlorine derivatives were involved in 18% of all incidents and 23% of all incidents resulting in victims. Victims were produced by 47 of 162 (29%) incidents. Respiratory exposures were the most frequent type of exposure and resulted in the largest number of victims transported to a hospital. Overall 24 of 26 (92%) incidents with chemical exposures resulted in symptomatic victims and 33 of 35 (94%) incidents produced victims requiring hospital transport. Respiratory symptoms were the most frequent, both in the number of incidents where they were observed and the total number of victims with symptoms. CONCLUSION Multiple victim transport to EDs from a single hazardous material incident is most likely to result from an inhalation exposure to a respiratory irritant. Information from descriptive studies should allow improved preparation for potential hazardous material victims.

Abstract
Hazardous materials releases can cause substantial morbidity and mortality, and an increasing number of communities have developed hazardous materials (HAZMAT) teams to deal with such incidents. Little is known, however, about the health effects of chemical accidents on HAZMAT team participants. Baseline and periodic medical surveillance of all 40 fire fighters from the Metrofire Haz-mat team was conducted in 1992/1993 and 1995, respectively. A database on incidents responded to by the team during the study period was also developed. From June 1990 through April 1995, the team responded to a total of 34 hazardous materials incidents. No injuries to HAZMAT team members were reported. Few biochemical abnormalities were observed, and those that were could not be linked to specific exposures or incidents. Four individuals had abnormal audiometry on both occasions. There was a trend toward a lower percent predicted FEV1 for the entire group on follow-up: 106 +/- 13% vs 105 +/- 12%, P = 0.07. For fire fighters older than age 35 (n = 21), the percent predicted FEV1 was significantly lower at follow-up: 108 +/- 12% vs 106 +/- 14%, P = 0.01. The results suggest significant noise exposure and exposure to pulmonary irritants, which support the use of baseline and periodic audiometry and spirometry. The potential utility of other laboratory testing is also discussed.
