Machinery Safeguards

OVERVIEW
Departments are to use safeguards to protect employees and students from hazards associated with operating machines. Machine safeguards are generally physical barriers that either enclose or isolate hazards.

When safeguards cannot be used during maintenance, service, and repairs, personnel are to disconnect and control (e.g., lockout) all machine power sources to prevent inadvertent activation. See 3.68.
RESPONSIBILITY

Departmental Administrators
Departmental administrators are responsible for ensuring that machines used for work, teaching, and research are equipped and maintained with appropriate safeguards.
Supervisors/Faculty
Supervisors and faculty are responsible for training employees and students in the proper use of machinery and safeguards in accordance with the manufacturer's instructions. This should be a part of the safety orientation. See 2.16.
Employees/Students
Employees and students must properly use machines and safeguards at all times. Safeguards may only be removed during maintenance, service, and repairs when power sources are disconnected and controlled (e.g., locked out). See 3.68.

Employees and students are not to wear loose clothing, neckties, rings, or other jewelry which could be caught or entangled in moving parts. Employees and students whose hair is long enough to be caught or entangled in moving parts are to wear caps, hair nets, or other protection which confines hair.
INSPECTION
Machines are to be inspected before each use in accordance with the manufacturer's instructions. This process includes inspecting the operating controls, safety devices and guards, electrical cords, power transmission devices, and points-of-operation for obvious defects.

Additionally, as part of the department's annual self-inspection, supervisors are to check all machine operations in order to identify hazardous areas or processes. See 2.50 for self-inspection procedures.
SAFEGUARDS
Obtain or design safeguards to completely enclose or prohibit access to hazards. The safeguards are to be securely affixed to the machine or other attachment points. The safeguards are not to create a hazard, e.g., cutting hazard.
Operations to Be Safeguarded
Safeguard the following two types of operations by using physical barriers that either enclose or isolate the hazard(s):
Examples
Examples of points-of-operation and power transmission points are:
See the PDF version of 3.62.2-3 for examples.
MACHINE CONTROLS
Machines are to be equipped with the following types of controls:
MACHINE GUARDING HAZARDS--REPORTING AND CORRECTION

Employees/Students
Report hazards directly to the supervisor or use a Hazard Notification form. See 2.52.

Do not use a machine designated as unsafe. Usually such machinery is tagged, posted, locked, fenced, or otherwise designated as unfit for use.

Resume operation only after the hazard has been corrected and the machine has been declared safe to use by a supervisor, faculty member, or qualified repair person.
Supervisors/Faculty
Upon observation or notification of a machine not equipped with proper safeguards, a supervisor or faculty member is to remove the machine from service.

Notify employees and/or students that the machine is not to be operated. Place a warning notification, e.g., tag or sign, on the machine designating it as unsafe and not to be opeated. Prevent use by disconnecting and locking out the power source(s) or other effective means, such as installing barriers or physically removing the machine.
