VICE PRESIDENT, SUPPORT SERVICES
SCOPE
This Safe Practice Instruction encompasses all employees at all Cessna facilities that are required to wear any
type of eye protection in the course of their job. This includes employees assigned to work in areas requiring eye
protection, visiting employees, contract workers, or any visitor entering any area requiring eye protection for any
reason.
Questions can be directed to:
Cessna Safety and Environmental Departments
ORGANIZATION COMPONENTS AFFECTED
All locations of Cessna Aircraft Company and its subsidiaries.
RESPONSIBILITIES
A. Each Manager, Foreman, and Supervisor shall implement and enforce all aspects of this Safe Practice
Instruction.
B. Each employee, contract worker, or visitor shall follow every aspect of this Safe Practice Instruction.
C. Employees failing to comply with this SPI will face disciplinary action in accordance with Cessna Aircraft
Company policy and procedures. Contract workers and visitors who fail to comply will be subject to
exclusion from the area.
WHEN EYE PERSONAL PROTECTIVE EQUIPMENT (PPE) IS REQUIRED
1.0
All eye protective equipment shall meet requirements of American National Standards Institute (ANSI)
Standard Z87.1.
1.1
Employees working in office areas are not required to wear protective eye wear while at their workstations.
1.2
Safety glasses with side shields are required for anyone walking/traveling in all manufacturing,
warehousing or service areas, including aisle ways unless the aisle way or area is specifically exempted
by the Safety Department.
1.3
Each affected employee shall wear appropriate eye protection when hazards from flying particles, molten
metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors are present, or when potentially
injurious light radiation exists. This eye protection shall provide side protection when there is a hazard from
flying objects. Detachable side protectors (i.e. clip on or slide-on side shields) meeting the requirements of
the Occupational Safety and Health Administration (OSHA) Standard 1910.133 (a) (2) are acceptable.
1.4
1.3.1
Employees engaged in drilling or grinding operations at shoulder height and above shall wear
goggles.
1.3.2
Employees working with corrosive chemicals or at risk from chemicals dropping onto their face shall
wear a chemical resistant goggle.
Each affected employee wearing prescription lenses while engaged in operations involving eye hazards
shall wear eye protection that incorporates the prescription in its design, or shall wear eye protection over
the prescription lenses. Wearers of contact lenses are required to wear appropriate eye protection devices

while engaged in operations involving eye hazards. It should be recognized that dusty and/or chemical
environments might present an additional hazard to contact lens wearers.
1.6
Photo chromic lenses shall not be worn by employees operating vehicles that pass from outdoors to
indoors because the color fading process of the lens is not instantaneous or considered protection in
hazardous optical radiation environments.
1.7
Shaded lenses with shade of more than level 1 (any tint) are not acceptable for indoor use unless safety
considerations dictate a darker shade (specifically selected and approved eye protection for use in
extremely bright light conditions, such as welder's hoods while welding or tinted goggles for use while
performing torch soldering or brazing, or work with a laser).
1.8
Employees needing eye protection from light radiation should use the following guidelines for the selection
of the appropriate lens tint.

Gas Welding (Light) up to 1/8 in.

Gas Welding (Medium) 1/8 to 1/2 in.
5 or 6
Gas Welding (Heavy) over 1/2 in.

NOTE: The choice of a filter shade may be made on the basis of visual acuity and may therefore vary widely
from one individual to another, particularly under different current densities, materials, and welding processes.
However, the degree of protection from radiant energy afforded by the filter plate or lens when chosen to allow
visual acuity will still remain in excess of the needs of eye filter protection.
1.9
"Mirror-surface" lenses are not acceptable in any application at Cessna, indoors or outdoors.
CLEANING, CARE AND FITTING OF EYE PROTECTION
2.0
Managers, supervisors and foremen are responsible for appropriate training requirements for eye
protection for employees working in their departments.
2.1
Consideration should be given to the comfort and fit of eye protection equipment. Devices that fit poorly
will not afford the protection for which they were designed. Prescription eyewear needs to be fitted by
qualified personnel.
2.2
Eye Protection should be cleaned according to the manufacturer's instructions. If no instructions are
available, clean the PPE with a mild soap and warm water solution by soaking the device in a soap
solution maintained at 120oF for ten minutes. Rinse thoroughly and allow to air dry. Eyeglass cleaning
stations are available throughout Cessna facilities containing a silicone-free cleaning agent and wipes.
2.3
Employees should make a visual inspection of their PPE prior to each use. Protective devices that exhibit
broken parts, heat distortion, or excessive scratches on the lens are unsuitable for use and should not be
worn.
2.4
Eye protection may be obtained through departmental PPE ordering procedures. Prescriptions glasses
may be purchased from Mid-West Lens (Truck) or through your optometrist as long as they are Ansi
Z87.1.
