As the delivery service market continued to increase, the number of delivery workers also increased, but the corresponding safety education is insufficient. Therefore, this study is going to explore the importance of safety education by grasping the relationship between safety awareness, accident experience, and safety behavior of delivery workers. With the help of the delivery workers' online community site, this study conducted a survey on the status of delivery workers' safety education for a total of 114 delivery workers. As a result of the association analysis, more than half of the general agency workers said they did not receive safety training, and delivery workers who completed safety training were 2.36 times more frequent than delivery workers who did not complete safety training. In addition, through correlation analysis and simple regression analysis, safety education had a positive effect on safety perception of delivery workers, and there was a significant correlation between safety perception and safety behavior. Through these, the relationship between safety education and safety awareness, safety behavior, and the number of accident experiences was noticed, and it was concluded that safety education should be mandatory on all delivery platforms to prevent accidents.

건설현장에서 작업환경측정을 하고 있으나 노출되고 있는 유해인자를 세분화하여 작업환경측정을 하지 않고 공정별 대표적으로 노출되는 소음, 진동 등 몇 가지만 실시하고 있다. 이에 건설현장에서 가장 많이 노출되는 산화규소분진의 유해성과 현재 건설현장에서 하고있는 개선대책의 보완점을 찾고자 한다. 연구방법: 안전보건공단과 산업보건협회에서 발행하는 실태조사 보고서 및 작업환경측정 기관의 자료를 활용하여 현황을 분석하였고 산업안전보건법의 작업환경측정에 관한 규칙과 비교 분석 하였다. 연구결과: 산화규소분진의 유해성을 파악하고 개선책을 보완도출하였다. 결론: 건설현장의 산화규소분진의 유해성을 도출하고 이에 따른 개선대책을 제시함으로써 현장에서 적극적으로 적용한다면 산화규소분진에 대한 직업병을 줄일 수 있을 것으로 기대된다.

대한민국의 심장인 서울 중심부에 위치한 안전보건공단 서울북부지도원은 강북지역 12개구(중구, 종로구, 마포구 등)를 관할하고 있다. 관할 지역 내에 국내 대표 건설업체의 본사들이 다수 존재하고 있으며, 유명 백화점과 음식점 등도 밀집돼 있다. 즉 건설 및 서비스업종의 작업적 특성과 안전보건현황을 빠르게 파악할 수 있는 환경을 갖추고 있는 것이다. 때문에 지도원은 이들 분야의 안전보건에 있어 고도의 전문성을 갖추고 있다는 평가를 받고 있다. 실제 지속적인 산재 감소와 우수한 사업수행으로 2011년도 경영평가에서 전국 1위(S등급), 2012년도 경영평가에서 A등급을 달성하기로 했다. 이런 성과 덕에 서울북부지도원은 건설안전의 산실(産室), 서비스업 산재예방의 메카로 불린다. 이처럼 큰 활약상을 보여 온 서울북부지도원이 최근 또 한 번의 도약을 준비하고 있다. 올해 초 부임한 이덕재 원장을 필두로 한층 더 다양한 산재예방 네트워크의 구축에 총력을 기하고 있는 것이다. 이 원장을 만나 향후 계획과 재해감소 방안 등에 대해 이야기를 나눠봤다.

Background: The use of scented candles and incense sticks, both of which are household products that are burned for indoor deodorization and calming effects, is increasing. Fine dust has been designated as a group 1 carcinogen by the International Agency for Research on Cancer. Volatile organic compounds (VOCs) affect air pollution and can cause diseases. Objectives: This study aims to determine the effect on indoor air quality by measuring PM_2.5 and VOCs generated when burning scented candles and incense sticks. Methods: Scented candles and incense sticks were selected as household products to burn. As for the target sample, top-selling products (five types of scented candles, five types of incense sticks) were purchased online. The PM_2.5 concentration according to time was measured immediately next to the sample and three meters away from each other in an enclosed space using a real-time aerosol photometer. VOCs were collected as samples under the same conditions using Tenax tubes and were quantitatively analyzed by TD-GC/MS. Results: In the case of scented candles, the concentration of PM_2.5 did not increase during combustion and after being extinguished by placing a cover on the candle. For the incense sticks, the concentration of PM_2.5 averaged 1,901.27 ㎍/m³. After burning scented candles and incense sticks, some VOCs concentrations were increased such as ethyl acetate and BTEX (benzene, toluene, ethylbenzene, xylene). Conclusions: Therefore, when using scented candles, extinguishment by placing a cover on the candle can be expected to reduce PM_2.5. It is advisable to avoid using incense sticks because PM_2.5 concentration increases from the start of combustion.

Background: The Korea Centers for Disease Control and Prevention (KCDC) has identified cases of people suspected of suffering lung disease potentially caused by chloromethylisothiazolinone/methylisothiazolinone (CMIT/MIT) used in humidifier disinfectants (HDs). The Korean Ministry of Environment (MoE) epidemiological investigation and toxicity test study found that HDs caused health damage such as asthma and lung disease. Objectives: The main purposes of this study were to classify the HD exposure rating and to analyze the exposure characteristics that affect exposure to CMIT/MIT HDs. Methods: The exposure characteristics and socio-demographic characteristics of victim participants using CMIT/MIT HDs were investigated through questionnaires. An inhalation no observed adverse effect level (NOAEL) for CMIT/MIT was produced based on inhalation toxicity values. Exposure ratings (class 1~class 2) were cross-tabulated with clinical ratings (acceptable~unacceptable). A correlation analysis was conducted with the main exposure characteristics that affect the exposure concentration of CMIT/MIT HDs. Results: The concentration in indoor air of CMIT/MIT was 8.75±25.40 ㎍/m³, and the exposure concentration was 2.30±6.29 ㎍/m³. The CMIT/MIT exposure rating of 67 participants with high exposures of not more than MOE 100 were evaluated as 14.5%, while the damage participants who matched the clinical rating made up 4.5%. The exposure concentration of CMIT/MIT showed a positive correlation with the daily usage amount and usage frequency, and a negative correlation with volume of the indoor environment. Conclusions: A new exposure rating could be suggested and calculated based on the MOE, and the factors affecting the exposure concentration could be identified.
