PHSRs就是Pre-Start Health & Safety Reviews ，针对到加拿大和美国的机械电气设备，特别是到加拿大安大略省的机械电气设备，需要进行健康安全检查，也就是PHSRs。
1. PHSRs介绍
截至2000年10月7日，政府制定新的健康安全法规(OHSA)，现在法律要求雇主对合格的新设备或改装设备执行启动前健康和安全评审（PHSR）。
2.什么是PHSR Pre-Start Health and Safety Review ?
在任何工人被允许操作任何机械，设备或危险环境中的过程之前，雇主有责任确保准备完整的报告，说明设备安全。 本PHSR报告要求审查与该特定类型设备有关的所有相关规定。
3.谁来执行PHSR?
根据OHSA的要求，审查必须由具有特殊专家或专业知识或资格的专业工程师（由省颁发）执行。
4. 是否需要PHSR 审查认证？
根据OHSA的规定，有一些例外，由专业工程师进行的PHSR是不需要的。 在这种情况下，雇主有责任确保豁免正确完成。 这包括保存和维护建立豁免的文件，并且只要设备仍然存在，就可以在工作场所随时访问。
5. PHSRs文件保存
在PHSR完成后，雇主必须：
确保报告在工作场所（包括任何支持文件）保持随时可用。
确保在设备运行之前将报告提供给其联合健康和安全委员会进行审查
6. PHSR的一些典型应用是什么？
触发对PHSR的要求的标准是相当详细的，并且根据情况而变化。在工业中，任何新设备或改装的设备，配备以下保护元件通常需要PHSR：
（即安全光幕，区域扫描系统，双手控制系统等）的安全保护装置，
使用互锁机械或电气安全装置（即钥匙进入系统）的物理屏障或安全围栏，
在PHSR期间要考虑的一些关键点是：
安全电路应由硬件接线或由安全PLC控制
安全电路应适当地设计用于应用（即典型地双通道或控制可靠）
安全防护必须正确：高度，远离设备，正确尺寸开口
设备必须配备安全进入机构
气动/液压回路在断电和设备进入情况下必须是功能安全的（即断电以防止受伤）
设备必须设计成安全地承受负载能力
安全措施必须是故障安全的 – 能够承受可能发生的单一故障
上述示例仅是在PHSR期间必须考虑的几个。对这些类型的申请的评估将涉及审查既定的标准和规章（即ANSI，CSA，MOL，ISO等）以及审查者的专业知识和经验。
PHSRs provides specialized engineering services dealing with Occupational Health and Safety as it applies to the workplace. Our firm is based in Ontario and we service clients throughout Canada and the USA.
It is our mission to ensure that your workplace is a safe environment and that workers are not exposed to operational hazards that may endanger their well being. Our engineers are very experienced at inspecting and evaluating industrial machinery to determine compliance requirements. Many engineering firms tend to focus on elaborate hi-tech compliance solutions which can be very expensive and are often detrimental to production. Our engineers will ‘go the extra distance’ and investigate simplified safety solutions which are reliable, inexpensive, and promote productivity. When choosing an engineering company, it is crucial to realize that the firm you select can substantially influence the overall equipment costs associated with any project. We know that the only way for us to earn your repeat business is to provide you with the best possible service always.
Although Pre-Start Health and Safety Reviews, (per OHSA Reg. 851) comprise a majority of our business volume, we also provide many other related services.
对于工程和安全我们提供的服务:
- Pre-Start Health and Safety Reviews (as per Reg. 851 of the Occupational Health and Safety Act)
- Engineering Safety Audits & Assessments – customizable per specific Ministry of Labour orders (e.g. 54(1)(f), 54(1)(k), stop work orders, etc.)
- Structural Approvals (e.g. racking systems, mezzanines, lift assists, etc.)
- Machinery Stop Time Analysis & Safe Distance Calculations
- Risk Assessments – we will guide you through the process of conducting a risk assessment supplying you with training and documentation so that you can repeat these methods elsewhere in the workplace
