A wet floor sign is used to warn people about wet floor and so prevent them from shipping and falling.In many countries,if an injury results from a wet floor,the owner may be found for the injuries.Sometimes wet floor signs are not enough.Effective behavior has been shown to be noticed when a wet floor warning is also presented every 10seconds by a tape player..And we can see this sign in the places for services. | |
A welcome sign (or gateway sign) is a road sign at the border of a region that introduces or welcomes visitors to the area.Examples of welcome signs can be found near political borders(邊界),such as when entering a state,province,county,city,or town,and they are increasingly found in neighborhoods and private communities. | |
These warning signs indicate (指示) that traffic lights are ahead,and are often used when it is difficult to see that a traffic light may already be showing red,to warn a driver to prepare to slow down.Some countries also have signs warning of signals for ramp (土堤斜坡) meters,fire stations,and airfields(little airport). | |
Warning signs are also found on other dangerous places.At the base of electricity pylons (高壓線塔)or equipment with open parts leading high voltage(電壓),there are signs warning of high voltage.Here is an International safety symbol"Caution (提示),risk of electric shock",also known as high voltage symbol.If you see this sign,you should be careful for danger. |
