“下班后，给机器润滑并清洁”—— 原始保加利亚珐琅工业安全标志

这块原始的保加利亚珐琅工业安全标志传达了工业工作世界中的一个实用信息：“След работа смажи и почисти машините”——“After work, lubricate and clean the machines。”

Produced during Bulgaria’s socialist period, most likely between the 1960s and 1980s, this sign reflects the working routines of factories, workshops, and industrial facilities across the Eastern Bloc. Workers were expected not only to operate machinery but also to maintain it properly at the end of each shift. Keeping machines clean and lubricated helped reduce wear, prevent breakdowns, and keep equipment ready for the next working day.

这一标志是在保加利亚社会主义时期制作的，很可能出现在1960年代至1980年代之间，它反映了东欧集团成员国的工厂、车间和工业设施的工作常规。工人不仅要操作机器，还要在每个班次结束时对设备进行适当维护。保持机器清洁并润滑有助于减少磨损、预防故障，并确保设备为第二天的工作做好准备。

Unlike signs warning of immediate danger, this piece represents another side of industrial life: the discipline, routine, and maintenance that kept factories running. Its straightforward wording and tall, bold red lettering were designed to make the instruction easy to read at a glance, even in a busy workshop.

与警示即时危险的标志不同，这一件作品展示了工业生活的另一面：维持工厂运转所需的纪律、日常性和维护。其直白的用语和高大、粗红色字体旨在让指示一眼即可读懂，即使在繁忙的车间。

The simple red-and-white design gives the sign a distinctive industrial appearance, while its original enamel finish and period typography preserve the look of vintage Bulgarian workplace signage. Surviving examples of this specific design may be uncommon, although its exact rarity has not been established.

简洁的红白配色赋予标志独特的工业外观，其原始珐琅表面和当时的排版风格则保留了保加利亚早期工作场所标识的复古风貌。就此特定设计的现存样本可能并不常见，尽管其确切稀缺性尚无定论。

Today, this sign offers a glimpse into the everyday working culture of socialist-era Bulgaria. Rather than advertising a product or commemorating a major event, it preserves an ordinary instruction from an industrial environment — a small but interesting detail of working life during the Cold War.

如今，这块标志让人一窥社会主义时期保加利亚的日常工作文化。它并非宣传产品或纪念重大事件，而是保存了来自工业环境的一条普通指令——在冷战时期工作生活中一个微小但有趣的细节。
