Inspecting for unsafe conditions
Use the information in this section to help you identify potential unsafe conditions in a Lenovo product
that you are working on.
Each Lenovo product, as it was designed and manufactured, has required safety items to protect users
and service technicians from injury. The information in this section addresses only those items. Use
good judgment to identify potential unsafe conditions that might be caused by non-Lenovo alterations or
attachment of non-Lenovo features or options that are not addressed in this section. If you identify an
unsafe condition, you must determine how serious the hazard is and whether you must correct the problem
before you work on the product.
Consider the following conditions and the safety hazards that they present:
• Electrical hazards, especially primary power. Primary voltage on the frame can cause serious or fatal
electrical shock.
• Explosive hazards, such as a damaged CRT face or a bulging capacitor.
• Mechanical hazards, such as loose or missing hardware.
