點樣用英文講解安全警告
安全同警告嘅字詞，可以幫你了解危險、跟從指示，並講解人哋應該點做。你可能喺工作場所、學校、住宅大廈、車站、公園、商店、酒店、健身室、診所同公眾活動入面用到呢啲字。與其淨係講「be careful」，你可以講有 hazard、地下好滑、呢個區域受限制、人哋應該避開入口，或者大廈必須疏散。
警告語言通常都好短，因為人哋要好快咁理解到。指示牌、廣播、標籤同職員指示可能會用到 caution、danger、emergency、keep clear、report、avoid 同 evacuate 呢啲字。學識呢啲字可以幫你冷靜咁應對，並清楚咁講出安全問題。
重點區分
Safety（安全）意思係免受傷害、損傷、破壞或者危險。安全規則係用嚟喺問題發生之前預防佢哋。
Warning（警告）係一個關於可能有危險嘅訊息。佢叫人哋留意同小心。
Caution（注意）意思係小心啲，因為有一定風險。佢喺指示牌同標籤上好常見。
Hazard（危險源）意思係危險嘅來源。濕地下、外露電線、被擋住嘅出口、鋒利邊緣，或者鬆脫嘅梯級，都可以係 hazard。
Risk（風險）意思係有壞事發生嘅機會。Hazard 會造成 risk。
Emergency（緊急情況）意思係需要即時行動嘅嚴重情況，例如火警、受傷、漏煤氣，或者保安威脅。

自然搭配
可以用 safety rule、warning sign、caution tape、serious hazard、safety risk、emergency exit、evacuation route、first aid kit、protective gear、wet floor、slippery surface、loose railing、blocked exit、restricted area、keep clear、avoid contact，以及 report the hazard。
動詞方面可以用 warn、avoid、report、protect、evacuate、injure、block、secure、inspect、repair、follow，以及 respond。
"Please keep the emergency exit clear."
"Report any safety hazards to staff."
"The floor is slippery after cleaning."
"Everyone must evacuate during a fire alarm."
"Wear protective gear in this area."
呢啲搭配好有用，因為安全語言會將一個危險同一個行動連繫起嚟。
例句
"The sign warns visitors about a slippery floor."
"There is a loose step near the back entrance."
"Do not touch the exposed wire."
"The area is restricted because repairs are in progress."
"Please keep clear of the loading zone."
"The fire alarm means everyone must evacuate the building."
"The first aid kit is in the office next to reception."
"A blocked exit is a serious safety hazard."
"Workers must wear protective gear near the machinery."
"Report spills immediately so no one slips."
睇懂警告指示牌
警告指示牌通常會用短語，而唔係完整句子。個訊息一般會話畀你知危險係咩，同埋要做嘅行動。
「Caution: wet floor」意思係地下可能好滑，所以要小心行。
「Danger: high voltage」意思係有嚴重嘅電力危險。
「Keep clear」意思係唔好企喺嗰度，亦唔好阻塞個區域。
「Authorized personnel only」意思係只有獲批准嘅職員先可以進入。
「Emergency exit」意思係呢個出口應該喺緊急情況時先用。
「Do not touch」意思係掂呢樣嘢可能唔安全，或者可能整壞佢。
呢啲指示牌好直接，但唔係冇禮貌。佢哋係特登設計成可以快速閱讀。
報告安全問題
當你報告一個 hazard，要包括地點、問題，同可能嘅風險。
"There is a spill near the elevator."
"The handrail on the stairs is loose."
"The emergency exit is blocked by boxes."
"A cable is lying across the hallway, and someone could trip."
"The light in the parking lot is not working."
之後如果有需要，就要求採取行動：
"Could someone put up a warning sign?"
"Please send maintenance to check it."
"Can you block off the area until it is repaired?"
"Who should I contact about this safety issue?"
具體嘅報告可以幫職員更快回應。「There is a hazard」嘅作用，遠遠不及「There is broken glass near the main entrance」。
學習者常犯嘅錯誤
唔好混淆 warning 同 warming。Warning 意思係關於危險嘅訊息。Warming 意思係令某樣嘢變暖。
唔好講「take care the floor」。要講「Be careful. The floor is slippery」或者「Watch your step」。
當你只係指唔方便嘅時候，唔好用 dangerous。Dangerous 意思係真係有受傷嘅風險。一條長龍係唔方便，唔係危險。
唔好混淆 risk 同 hazard。Hazard 係嗰樣會造成傷害嘅嘢。Risk 係傷害會發生嘅機會。
喺大多數簡單指示入面唔好講「evacuate from the building」。要講「evacuate the building」或者「leave the building」。
唔好忽略警告指示牌上嘅行動字眼。好似 avoid、keep clear、do not enter、report 同 evacuate 呢啲字，會話畀你知要做咩。
實用範例段落
During the community event, staff noticed several safety issues near the entrance. Rain had made the floor slippery, so they placed a caution sign and asked visitors to walk carefully. A power cable was also lying across the hallway, creating a trip hazard, so maintenance secured it with a cover. Later, someone blocked an emergency exit with extra chairs, and a volunteer moved them immediately. Staff reminded everyone to keep exits clear and report any hazards to the information desk.
好嘅安全描述會講出 hazard、解釋風險，並畀出正確嘅行動。用 caution、warning、hazard、risk、emergency、avoid、keep clear、report 同 evacuate 呢啲字，可以令指示清楚又實用。
