防坠落安全带有明确的有效期吗? (Re: MSA)
In the News
In a recent article, we discussed the “expiration date” for hard hats. 从技术上讲,它们没有标准定义的EOL(生命终止)日期或确定的保质期. 毕竟,我们不是在谈论食物或其他易腐物品. That said, 大多数制造商确实根据制造日期和/或首次使用日期制定了检查和更换某些部件的指导方针.
But what about fall protection harnesses?
是否有一个防摔装置的有效期限,超过这个期限就不能使用了?
The answer is both yes … and no. Here’s why.谁来定义防摔安全带的有效期或使用寿命?
不存在预先确定或强制规定的坠落保护装置的失效日期. OSHA和ANSI都没有现行的规范或标准来规定线束停止使用的具体澳门新葡京官网app. 即使大多数制造商也不会建议一个线束将持续多长澳门新葡京官网app.
In fact, 唯一能真正决定何时解除脊甲的人是你或你的主管, trained inspector. 比谁决定生命的终结更重要的是什么决定生命的终结.The Potential Problem With a Mandated Expiration Date.
你可能会认为,为防摔安全带设定一个强制有效期是件好事. However, it could have some adverse effects.
例如,它可能会让佩戴者或安全专业人员产生一种虚假的安全感.
“我的马具才用了一年,所以我相信我得到了充分的保护. This harness still has four year of use left in it.”
See the problem?
It’s possible to become complacent, 想当然地认为如果需要,安全带会正常工作. 佩戴者可能会在每次使用背带时跳过检查缺陷. Additionally, 虚假的安全感可能导致推荐人年检推迟甚至跳过.
影响防摔装置使用寿命的因素
As with any PPE (personal protective equipment), 必须爱护和正确使用全身防摔安全带. Some of the things that affect them adversely are:
钩在突出的物体上,可能导致背带的织物或缝线撕裂. 这可能会造成一个弱点,在摔倒时可能会失败.
涂料或饱和的油漆和其他化学品会削弱织带施工中使用的合成材料. Remove this materials as soon as possible, 使用制造商的指导方针,以避免进一步恶化.
过度暴露在紫外线或阳光下可能会导致合成纤维变质或变弱. 当线束不使用时,将其存放在远离阳光的地方.
接触苛性碱和酸可能会损坏金属部件,如d形环和扣环. Clean this items as soon as possible using approved methods.
Improper storage methods can damage the harness. 安全带应该放在一个悬挂的位置,这样织带就可以“放松”.” Hang the harness by the D-ring, not the webbing.
任何有防坠装置的挽具必须立即停止使用. Do not use the harness after the impact event. 它必须贴上不能使用的标签,并在损坏之前停止使用.确定线束可用性的唯一方法是通过例行检查.
仔细检查线束是否损坏是确定其状况的唯一可靠方法. 这包括佩戴者在佩戴设备前的使用前检查和由合格人员进行的定期检查, competent inspector.
合格的检验员应接受适当检验程序的培训,并应将每个吊带的检验记录在日志单上. While the pre-use inspection is necessary, 检查员对设备的仔细检查确保线束被正确检查.
ANSI建议每隔不超过6个月进行一次正式检查. 检查员不应该是佩戴那种特殊挽具的人. 如果可能的话,使用的日志表应该与确切的线束相匹配.
我们建议在6个月内未经过正式检查的线束应停止使用并标记为不可用,直至正式检查完成, including documentation.
A Five Step Procedure for Harness Inspection
这里有五个步骤,你应该遵循进行正式的审查.
Inspect all webbing and stitching
- You’re checking for cuts, fraying, pulled or broken threads, abrasions, excessive wear, altered or missing straps, burns, UV damage, and heat and chemical exposures. Starting at one end of a webbing length, 双手分开8英寸抓住织带,弯曲织物. 这可以暴露任何缺陷,没有看到与织带在一个直线对齐.
Inspect all metal or plastic components of the harness
- 所有安全带扣应工作自由,接合和分离充分和顺利. Depending on the model harness you use, make sure each type of buckle, including a quick connect buckle, is functioning properly.
- Look for deformation, crack, corrosion, deep pitting or burrs, sharp edges, nicks or cuts, exposure to excessive heat or chemicals, and any other damage. Missing, loose or improperly working parts should be noted. This should include both metal and plastic components.
- d形环不应有裂纹、变形或其他损坏.
- Inspect all load indicators
- 负载指示器是束带的部分,折叠和缝合安全. Ripped stitching, even if only partially separated, 是否有迹象表明安全带已经坠落,不再新葡京app提供足够的保护. Remove the harness from service immediately. Mark it as unusable until such time as it can be destroyed.
Inspect all labels
- 为了完全通过检查,标签必须存在且可读. 确保线束的唯一标识符清晰可辨,以便在日志表上正确标记.
Complete All Inspection Documentation
- 正式的检查是在填完文件后才进行的. 如果有必要,创建一个日志表,覆盖您使用的线束的所有检查点.
Many suppliers, like MSA Safety, can furnish you with a complete, fully itemized inspection log for each model they sell. Your log should have a place to enter condition codes, overall assessment scores, and room for the inspector to make comments.
请记住,评估并不是按浮动比例进行的. 无论组件是什么,都会获得合格或不合格评级. There is no in-between.
