RPN at 100 signals action within the study; severity nine bypasses straight to a project; PFD 0.1 qualifies an IPL with SIL bands below; HAZOP's five columns skeleton the answer; the log-scale matrix steps one band per decade. Compute when asked, grade when described.
常见误解 / Common misread:误区:SIL 数字与 PFD 割裂记。SIL 档位就是 PFD 区间,一张卡两面。 Myth: SIL apart from PFD. The band is the interval.
Oxygen under 19.5 or over 23.5; the three LEL bands; 85 action and 90 PEL; thirty centimeters for the sampling head; thirty-year records under 1910.1020. Five gates, five item families.
常见误解 / Common misread:误区:30 年记成 20 年。医学去除记录保存期=就业期+30 年。 Myth: twenty years. Exposure records run employment plus thirty.
Fire watch thirty minutes after hot work; eleven meters of cleared fuel, plus covers over floor openings; waste 90/180 by category; CERCLA immediate call plus written; ERG green pages for distances. All clocked — items love asking what remains.
常见误解 / Common misread:误区:看火 30 分钟与 ERG 距离混用。一个管动火后,一个管运输初始响应。 Myth: mix the watch and the ERG. One follows hot work; one opens transport response.
Four Kirkpatrick levels landing at three; observation at 30/60/90 days; 40-hour general and 24-hour occasional cleanup; triennial forklift retraining behind an evaluation; baseline audiograms within six months. Any 'how long' item shops here.
常见误解 / Common misread:误区:40 小时与 24 小时倒置。一般暴露清理 40、偶发受控 24。 Myth: flip 40 and 24. General cleanup takes forty; incidental takes twenty-four.
