Learn to prepare an OSH technical description for compliance This article outlines the required structure for documenting workplace risks safety protocols and equipment Defining Technical Requirements for Occupational Safety and Health A robust employee protection document must begin by quantifying operational risks Immediately assign a Risk Priority Number RPN to each identified hazard derived from multiplying scores for severity likelihood of occurrence and detection difficulty For instance a hydraulic press with a known failure rate would receive a high score for severity and occurrence mandating the implementation of engineered controls over simple administrative warnings Detail the precise control measures for every identified risk This section requires specifics such as listing the exact model of required Personal Protective Equipment PPE for a task like specifying 3M 8210 respirators for silica dust exposure Furthermore it should contain stepbystep LockoutTagout LOTO sequences for individual machines not a generic policy For httpsspinbettercasinode reference the specific handling and firstaid instructions from the substances Safety Data Sheet SDS This detailed breakdown serves as a direct source for training materials and incident response plans It must contain clear schematics of emergency stop locations and evacuation paths The document should also outline a strict protocol for incident reporting detailing the immediate actions for supervisors to secure an area and preserve evidence for a root cause analysis feeding information directly back into the risk assessment process for continuous refinement Structuring an OSH Technical Description for Maximum Clarity Begin the document with a Summary of Controls table This table must itemize each hazard and its corresponding mitigation Columns should include Hazard Identifier Control Measure Applicable Standard eg ISO 450012018 section 812 Verification Method and the Designated Responsible Party This frontloads the most critical information for immediate review and action Organize the main body following a strict generaltospecific hierarchy Section 10 should define the Scope and Applicability clearly stating which machines processes or work areas are covered Section 20 Hazard Identification must list all identified risks categorized and numbered for direct reference eg 21 Mechanical 22 Chemical Exposure Structure the Control Measures section to mirror the hazard identification A section on 21 Mechanical Hazards must be followed by 31 Mechanical Control Solutions Use subsections for granular detail such as 311 Guarding Specifications and 312 Interlock System Logic Include precise data material types eg 3mm polycarbonate sheeting performance levels PLd per ISO 138491 and references to engineering diagrams Dedicate distinct sections to operational protocols and upkeep Create a Safe Work Procedures section detailing stepbystep instructions for operators Follow this with a LockoutTagout LOTO Protocol specific to the equipment A Maintenance and Inspection Schedule in a tabular format should specify Component Inspection Frequency PassFail Criteria and Required Action on Failure Isolate supplementary information in appendices to maintain focus in the main document Use Appendix A for the complete Risk Assessment Matrix Appendix B for manufacturers data sheets on safety components and Appendix C as a template for Training and Competency Records This organization separates reference material from direct instructions Pinpointing JobSpecific Hazards and Evaluating Risks Deconstruct each job function into a sequence of individual tasks For every task document potential sources of harm using direct observation worker interviews and incident records Categorize these sources with precision Physical Hazards Identify specific energy sources Examples include noise levels exceeding an 85 dBA 8hour timeweighted average electrical circuits operating above 50 volts or fall heights greater than 2 meters without fall arrest systems Chemical Hazards Reference Safety Data Sheets SDS for all substances used Pinpoint tasks involving potential exposure above Permissible Exposure Limits PEL such as handling toluene without proper ventilation or mixing cleaning agents that can produce chlorine gas Ergonomic Hazards Quantify physical stressors This includes tasks requiring more than 10 kilograms of force per exertion repetitive handwrist motions for more than two hours per shift or maintaining static awkward postures like neck flexion beyond 30 degrees Biological Hazards Specify the infectious agents or organic materials present Document exposure risks to bloodborne pathogens from needlesticks in clinical settings or fungal spores during demolition of waterdamaged buildings Psychosocial Hazards Detail work organization factors that produce stress Note highdemand lowcontrol work cycles lone work scenarios with risk of violence or irregular shift schedules that disrupt sleep patterns After pinpointing hazards appraise the associated risk by correlating the likelihood of an incident occurring with the severity of its potential consequences This creates a clear basis for prioritizing control measures Define Severity Levels Catastrophic Results in multiple fatalities permanent total disabilities or loss of the facility Critical Leads to a single fatality permanent partial disability or major property damage Marginal Causes an injury or illness resulting in lost workdays Negligible Requires only firstaid treatment no lost work time Establish Likelihood of Occurrence Frequent Expected to occur repeatedly during the systems life Probable Will occur several times Occasional Likely to occur sometime Remote Unlikely but possible to occur Improbable So unlikely that it can be assumed it will not occur Combine severity and likelihood to assign a Risk Assessment Code RAC A task with a Marginal severity and Frequent likelihood eg minor cuts from handling sheet metal daily may demand more immediate resource allocation for controls than a task with a Catastrophic severity and Improbable likelihood eg a structural collapse This structured appraisal directs resources toward the most pressing dangers Detailing Control Measures and StepbyStep Operating Procedures Apply control measures following a strict hierarchy prioritizing methods that remove the hazard entirely before resorting to personal protection This sequence ensures a more robust and reliable system for incident prevention Hierarchy of Hazard Mitigation Elimination Physically remove the source of harm httpsspinbettercasinode Decommission outdated highpressure hydraulic presses and replace the process with robotic arms using lowforce electric actuators Substitution Replace a hazardous material or process with a less hazardous one Example Substitute isocyanatebased paints with waterbased acrylic coatings to remove a respiratory sensitization risk Engineering Controls Isolate people from the hazard through physical modifications Example Install fixed guarding on all rotating machine parts interlocked with the power supply via a Category 3 safety circuit Implement local exhaust ventilation LEV systems with a capture velocity of 100 feet per minute at the source of fume generation Administrative Controls Change the way people work Example Implement mandatory job rotation schedules for tasks involving repetitive motion limiting any single operators exposure to two hours per shift Restrict access to areas where noise levels exceed 85 dBA to authorized personnel with documented audiometric testing Personal Protective Equipment PPE Equip the worker with protection This is the final line of defense For handling concentrated sulfuric acid require butyl rubber gloves minimum 15 mil thickness chemical splash goggles meeting ANSI Z871 and a fullface shield Standard Operating Procedure LockoutTagout LOTO for Machine Maintenance This procedure applies to all maintenance activities requiring personnel to place any part of their body into a machines point of operation Preparation The authorized employee must identify all energy sources electrical pneumatic hydraulic gravitational using the machinespecific energy control map posted at the main control panel Notification Inform all affected operators and supervisors of the impending equipment shutdown and the duration of the maintenance work Shutdown Follow the normal machine shutdown sequence Press the main OFF button and ensure all moving parts have come to a complete stop Isolation Physically deenergize the equipment Open the main electrical disconnect switch Close and secure all upstream hydraulic and pneumatic line valves Lock and Tag Application Apply a personal lock and a completed DANGER DO NOT OPERATE tag to each energy isolation point The tag must identify the worker performing the maintenance and the date Stored Energy Release Verify the release or blocking of all stored energy Bleed pneumatic lines to zero pressure block or pin any elevated parts against gravity and test for capacitor discharge where applicable Verification of Isolation Attempt to start the machine by pressing the ON button or activating normal controls This action confirms that the energy sources are isolated Return all controls to the OFF position immediately after the test The equipment is now ready for service Defining Emergency Response Actions and Assigning Clear Responsibilities Assign an Emergency Coordinator with the authority to manage incidents and halt operations This individuals contact information must be posted at all communication points For each potential incident such as a fire chemical release or medical situation create a specific action checklist For example a chemical spill protocol must detail 1 The exact alarm signal to use 2 Immediate evacuation distance and direction 3 The internal contact number for the response team 4 The specific Personal Protective Equipment PPE required from spill kits identified by location 5 The procedure for using containment booms and absorbent materials Implement a Responsibility Assignment Matrix RACI chart to eliminate confusion Define who is Responsible Accountable Consulted and Informed for every task The Emergency Coordinator is accountable for the overall response Floor Wardens are responsible for sweeping their assigned zones performing headcounts at muster points and reporting personnel status First Aid providers certified and listed by name and work area are responsible for initial medical care All other personnel are responsible for knowing evacuation paths and reporting procedures Mandate rolespecific training and regular drills First aid personnel must maintain current certifications Hazardous material teams require 24hour or 40hour HAZWOPER training depending on their duties Conduct evacuation drills semiannually and a tabletop exercise for a nonfire scenario annually Following each drill the Emergency Coordinator must lead a debriefing session to identify failures The emergency plan must be formally amended with corrective actions within 30 days of any drill that reveals a deficiency
