MACHINE SHOP SAFETY PLANINTRODUCTIONIn the academic teaching and research environment, machine shops pose a unique set ofchallenges in terms of risks to users. The current safety protocols established by the Center forEnvironmental Health and Safety do not specifically address these risks or associated hazards.The purpose of this Machine Shop Safety Plan is to provide guidance to all students andemployees in the (Name of work unit) at Southern Illinois University(SIU) Carbondale who work with machining tools and equipment in order to ensure a safe andproductive work environment.The Dean (or supervisor, responsible party, etc.) will designate and authorize an individual theMachine Shop Safety Administrator (MSSA). The MSSA will have thorough knowledge of propermachine operation and safe working procedures. The MSSA will manage all activities thatimpact machine shop safety, including user training, proper use of personal protectiveequipment, project set up, removal of unsafe machines from service, posting of appropriatesignage at work areas, and approval of users in the shop. After a user has gone through basicsafety training and training of a specific piece of equipment or machinery, the MSSA willapprove individuals to use specific equipment, and maintain records of the training. The MSSAwill have the authority to determine who is allowed into the shop. The MSSA will also serve asa liaison to the Center for Environmental Health and Safety.EMERGENCY PROCEDUREImmediately contact 9-1-1 via SIU landline or 453-3771 via cellphone to get the Department ofPublic Safety (DPS).*If a 911 is dialed via cellphone, you will get the state police*Next, report the incident to the MSSA and complete the “Report of Injury/Incident/HazardForm” on the Center for Environmental Health & Safety (CEHS) website( health/forms.html)FILESA binder will be kept in the machine shops with the following information: Machine Shop Safety PlanRecords of TrainingAnnual Inspection Forms

Students will be issued a card that shows their training. Students will be required to have thiscard on them when they are working in the machine shop.STUDENT RESPONSIBILITY Must use the buddy system when working in the shopMust complete the general training and arrange with the MSSA for machine specifictraining before using any machine.Must observe all shop safety rulesMust report all injuries to the MSSA, regardless of seriousness.Must promptly report unsafe conditions, actions or near-miss incidents to the MSSASHOP EQUIPMENT HAZARD CLASSIFICATION MATRIX (APPENDIX A)A hazard analysis of the most common types of equipment used in the (Namework unit) has been completed. This analysis has resulted in various pieces of shop equipmentbeing placed into one of three hazard categories: low, medium, or high. The type of equipmentpresent within a given shop will therefore determine the corresponding hazard category.The matrix located in Appendix A of this document details a number of shop requirementsassociated with each hazard category. These requirements have been established in order toprovide a safe working environment within University shops. The points within the tableinclude the following: The three hazard levels (low, medium, and high) are noted at the top of the matrix.The “general design” category contains a basic explanation of the size and power ofshop equipment categorized in each hazard level.The “common examples” category is a listing of the common equipment types that fitthe criteria for each hazard level.GENERAL SAFETY TRAININGRefer to Appendix CMACHINE AND EQUIPMENT TRAININGThe following information is provided as a guide for the minimum safety training that shall beprovided to personnel prior to authorized use of any machining tools or pieces of equipment.An authorized user must score 100% on the General Safety Training prior to testing on any ofthe machinery or equipment. An authorized user must score 100% on a safety test in order touse any individual piece of machinery or equipment.

NOTE: Machine shop personnel have been asked to provide a list of basic safety tips for eachpiece of machinery in their shop.FAILURE TO FOLLOW MACHINE SAFETY PROTOCOLS First time failure to observe all safety procedures will result in a warning.Second time failure to observe all safety procedures will result in a loss of access to themachine shop.Access can only be reinstated with a petition to and approval by the Dean andDepartment Chairs (or supervisor, responsible party, etc.).DEFINITIONSAdequate Facility – a facility which provides satisfactory clearance, power, light and ventilationAuthorized User – an employee or student who has received both general machine shop safetytraining and specific machine tool and equipment training administered by the appropriatemachine shop personnelBuddy System – a system designed to protect and assist the user in case of injury. During offhours when the machine shop is unsupervised, a “buddy” would be present so that, in theevent of an injury, emergency assistance is not delayed.Guard – an enclosure designed to restrain pieces of abrasive wheels, wheel pulley assemblies,or other moving parts or working stock, and to protect the employee in the event of breakageor accidental contact with the moving part.Machine Shop – a facility which may contain at least one of the following pieces of equipment:drill press, lathe, band saw, table saw, mill, grinder buffer, shear, metal punch, jointer, portablepower tools, swing arm saw, radial arm saw, planer, slitter, roll-form machine, cold header,multi-slide machines, drum sanders, belt sanders, splicers and alligator sheers.Machine Shop Safety Administrator – person designated to maintain the safety of the machineshop.REFERENCEThis guide is adapted from the best practices outline for the Shop Safety Policy of ColumbiaUniversity, the Occupational Safety and Environmental Health guidelines for Machine ShopSafety for Academic Departments used at the University of Michigan and the Machine ShopSafety Program at Pennsylvania State University.
