Objective. To provide a basis for the effective prevention of the same type of poisoning events through analyzing the causes of an occupational acute simple asphyxiating gas poisoning incident.Method. Descriptive epidemiological method was used to investigate the related personnel of the poisoning incident, detect poisonous and harmful gases in the air of the scene, and collect and analyze the clinical data of patients.Result. The poisoning incident led to 1 death and 2 poisoning. All of them were male. The dead patient was 38 years old, and two injured patients were 37 and 31 years old, respectively. The day after the accident, the contents of phenol, toluene, hydrochloric acid and oxygen were determined in the reactor where the accident occurred. The results showed that the maximum concentration of phenol, toluene and hydrochloric acid (CM) was 0/m3 , which did not exceed the occupational exposure limit of harmful factors in the workplace stipulated by GBZ2.1–2007. Also, the oxygen content was 10.0%, which was lower than the oxygen content in normal air.Conclusion. This is an acute simple asphyxiating gas poisoning incident caused by the employing unit managers and operators’ weak awareness of occupational hygiene and safe operation. The employing unit managers and operators should strengthen occupational safety training, strictly implement the occupational health management system, and prevent such incidents.Funding.

This chapter focuses on conducting worksite investigations, including walkthrough surveys, and provides occupational health and safety personnel, employees, and employers the opportunity to identify and assess current workplace conditions and employee health concerns and make recommendations on how to reduce or eliminate any identified workplace hazards. The methods described cover ways to implement corrective actions necessary for preventing future adverse incidents and to identify shortcomings in safety and health management programs. Various specific examples are provided. The National Institute for Occupational Safety and Health Hazard Evaluation Program, which has experience with all types of workplace hazards, is described. Preparing for and conducting workplace investigations is described in detail.

Carbon Dioxide Co2

Cabin air quality and thermal conditions have a direct impact on passenger and flight crew’s health and comfort. In this study, in-cabin thermal environment and particulate matter (PM) exposures were investigated in four China domestic flights. The mean and standard deviation of the in-cabin carbon dioxide (CO2) concentrations in two tested flights are 1440 ± 111 ppm. The measured maximum in-cabin carbon monoxide (CO) concentration is 1.2 ppm, which is under the US Occupational Safety and Health Administration (OSHA) permissible exposure limit of 10 ppm. The tested relative humidity ranges from 13.8% to 67.0% with an average of 31.7%. The cabin pressure change rates at the end of the climbing stages and the beginning of the descending stages are close to 10 hPa·min−1, which might induce the uncomfortable feeling of passengers and crew members. PM mass concentrations were measured on four flights. The results show that PM concentrations decreased after the aircraft cabin door closed and were affected by severe turbulences. The highest in-cabin PM concentrations were observed in the oldest aircraft with an age of 13.2 years, and the waiting phase in this aircraft generated the highest exposures.

Digital games have been successfully applied in different working sectors as an occupational safety training method, but with a very limited application in agriculture. In agriculture and other productive sectors, unintentional injuries tend to occur with similar dynamics. A literature review was carried out to understand how occupational risks are addressed during game-based safety training in different productive sectors and how this can be transferred to agriculture. Literature about “serious game” and “gamification” as safety training methods was searched in WEB OF SCIENCE, SCOPUS, PUBMED and PsycINFO databases. In the forty-two publications retained, the computer was identified as the most adopted game support, whereas “points”, “levels”, “challenges” and “discovery” were the preferred game mechanics. Moreover, an association can be detected between the game mechanics and the elements developed in the game. Finally, during the game assessment, much positive feedback was collected and the games proved to be able to increase the operators’ skills and safety knowledge. In light of the results, insights are provided to develop an effective, satisfying and engaging safety game training for workers employed in agriculture. Games can be best used to learn and they are certain to improve over the next few years.

In this study, an analysis of independent studies dealing with occupational safety training in different learning environments, in which various learning materials are used, was carried out. As a method, meta-analysis method was used. For this purpose, databases were used to collect national and international articles and papers suitable for the purpose of the study. Studies that did not mention the tools, equipment and environment used in education in the collected studies were excluded from the research, and 18 studies were included in the meta-analysis. The data obtained studies are categorized according to the education models, the sectors in which the education is applied and the characteristics of the participants in the education. As it is known, occupational health and safety procedures aim at a healthy and reliable working environment for its employees. However, the ultimate goal is to raise not only employees but also future generations with this awareness. The most important instrument of this is undoubtedly education. For this reason, it is necessary to develop training models suitable for the work environment, age, gender and every conceivable situation.
