木屑暴露的危险

Wood dust is a dangerous and widespread workplace hazard that can cause serious health problems if improperly managed. 确保职工安全、健康 & Safety Executive (HSE) is currently conducting inspections of woodworking businesses throughout the UK to prevent harmful exposure to wood dust. 在本文中, Expert Parmjit Gahir explores the risks associated with 木屑暴露 and examines the various measures that employers must take to protect their workforce

什么是木屑? 

Wood dust is the term used to describe the fine particles produced during woodworking activities such as cutting, 砂光, 塑造木材. 这些颗粒如果被吸入，可能对呼吸系统健康构成重大威胁. 不同类型的木材会产生木尘, which can contain allergens and potentially toxic substances depending on the type of wood and treatments or finishes applied to it. Although wood dust may seem harmless, inhaling it can lead to various health problems. 因此, woodworking businesses must acknowledge this danger and take necessary steps to address it.

与木屑有关的健康问题

The dangers of 木屑暴露 go far beyond being a mere nuisance in the workshop. Inhalation of wood dust can result in debilitating respiratory conditions such as bronchitis, 鼻炎, 和鼻窦炎. 长时间接触某些类型的木屑, 像硬木粉, 会导致更严重的健康后果吗, 包括职业性哮喘和各种癌症. 例如, the International Agency for Research on Cancer (IARC) has identified hardwood dust as a Group 1 carcinogen, 也就是说它对人类是致癌的, 尤其是鼻腔. These health risks underscore the importance of implementing effective control measures to minimize 木屑暴露 in the workplace.

接触多少木屑是危险的? 

Determining the threshold of 木屑暴露 that poses a danger to health is vital for employers and regulatory authorities. The Control of Substances Hazardous to Health (COSHH) Regulations 2002 set Workplace Exposure Limits (WELs) for both hardwood and softwood dusts. These limits specify the maximum concentration of wood dust that workers can be exposed to over a particular period without adverse health effects. 

对于硬木粉尘, WEL设定为3 mg/m3, 而对于软木粉尘, 根据8小时时间加权平均值设定为5毫克/立方米. 
Compliance with these limits is essential in safeguarding workers' respiratory health and minimizing the risk of long-term complications

如何控制接触木屑?

Effective control of 木屑暴露 requires a multifaceted approach that addresses both the source of dust generation and worker exposure:

• 工程控制: 实施除尘系统，如 局部排气通风或LEV，从源头捕获并去除空气中的微粒. LEV systems can be integrated into woodworking machinery or workstations to control dust emissions and minimize worker exposure.
• 个人防护装备: 为员工提供适当的呼吸防护设备, 例如防尘口罩或呼吸器, 尽量减少直接接触木屑. It's essential to ensure that PPE is properly fitted and maintained to maximize its effectiveness in protecting workers' respiratory health.
• 工人培训和意识: Educating employees about the risks associated with 木屑暴露 and fostering a culture of safety in the workplace. Employees should receive comprehensive training on the proper use of control measures, 安全工作守则, and the importance of reporting any concerns or issues related to 木屑暴露.
