警告标志
本手册使用以下标志提示潜在危险，这些危险可能或必然造成人身伤害或重大财产损失。根据危险发生的可能性，以及可能造成的人身伤害或财产损失的严重程度，共分为三个等级。
Warning sign (warning triangle) | Draws attention to the hazard |
Signal word | Identifies the degree of hazard |
Type of risk | Specifies the type or source of the hazard |
Consequences | Describes the consequences of non-compliance |
Precautions | Specifies how the hazard can be prevented |
Warning sign, signal word | Meaning |
| | Indicates a dangerous situation which will cause death or severe personal injuries if not avoided. |
| | Indicates a dangerous situation which may cause death or severe personal injuries if not avoided. |
| | Indicates a dangerous situation which may cause minor or medium personal injuries if not avoided. |
| | Material damage: the product or its environment could be damaged. |
| |
Danger from excessively high pressure! Danger to life or risk of injury, damage to equipment! Using the valve above the permissible maximum pressure can cause valve burst and hydraulic fluid to escape under high pressure.
|
Pressurized valve Danger to life risk of injuries when working on valve in system not being depressurized.
|
| |
Unsafe work on the valve Danger to life or risk of injury, damage to equipment!
|
| |
Escaping oil mist! Risk of explosion, fire health hazard, environmental pollution.
|
Static discharge Cleaning the valve with a dry rug may lead to explosions through electrostatic discharge that may cause severe injuries and even death.
|
Lack of grounding Risk of explosion that may cause severe injuries and even death.
|
Painting Risk of explosion that may cause severe injuries and even death.
