Purchase fire extinguishers, fire blankets, escape respirators, and first-aid kits, then inspect them once a year

备齐灭火器、灭火毯、逃生呼吸面罩和急救包,每年检查一次

Source cost

A set of fire extinguishers, fire blankets, one respirator per person, and a first-aid kit costs a few hundred yuan. You only need to buy it once; after that, it takes just 10 minutes each year to inspect the items.

Source return

Fire extinguishers, fire blankets, escape respirators, and first-aid kits are all included in the Emergency Management Department’s list of 11 essential items for household emergency preparedness. The whole set costs a few hundred yuan, and you only need to buy it once. Studies of home safety programs that included on-site guidance found these measures cut injury rates by roughly 25%.

THE LOW-ROI DETOURSatire, not advice

Move “Purchase fire extinguishers, fire blankets, escape respirators, and first-aid kits, then inspect them once a year” to Future Me's calendar

The excuse

There is no immediate alarm, so the sensible choice can wait for a less busy week.

What feels good now

Today I keep a little money, a few minutes and avoid interrupting my default routine.

What the source says

The source summarizes the return this way: “Fire extinguishers, fire blankets, escape respirators, and first-aid kits are all included in the Emergency Management Department’s list of 11 essential items for household emergency preparedness. The whole set costs a few hundred yuan, and you only need to buy it once. Studies of home safety programs that included on-site guidance found these measures cut injury rates by roughly 25%.” Evidence grade B. The original states the population, caveats, and sources; this is not a personal forecast.

26. Purchase fire extinguishers, fire blankets, escape respirators, and first-aid kits, then inspect them once a year

Cost: A set of fire extinguishers, fire blankets, one respirator per person, and a first-aid kit costs a few hundred yuan. You only need to buy it once; after that, it takes just 10 minutes each year to inspect the items.

In plain terms: Fire extinguishers, fire blankets, escape respirators, and first-aid kits are all included in the Emergency Management Department’s list of 11 essential items for household emergency preparedness. The whole set costs a few hundred yuan, and you only need to buy it once. Studies of home safety programs that included on-site guidance found these measures cut injury rates by roughly 25%.

Benefit: The Emergency Management Department’s “National Recommended List of Basic Household Emergency Supplies” contains 11 items in total. Among them, “fire extinguishers and fire blankets” are recommended for “putting out small fires at the initial stage”, and the list also notes that “fire blankets can be draped over the body to aid escape”. The “escape respirators” listed are “firefighting filtering self-rescue respirators designed for use during fire escapes”. “External medical supplies” refer to “hemostatic powder, adhesive bandages, gauze bandages, and other items used to treat wounds”. Cochrane analyzed 98 studies involving 2,605,044 participants in total. Home safety interventions lowered injury rates to an IRR of 0.89; the 95% confidence interval for this figure is 0.78 to 1.01. For interventions that included on-site guidance, injury rates dropped by around 25% (IRR 0.75, 95% CI 0.62 to 0.91).

Notes: This finding is somewhat controversial. The same Cochrane meta-analysis found that interventions that did not provide emergency supplies also lowered injury rates by roughly 20%. The original IRR for those interventions was 0.78, with a 95% confidence interval of 0.66 to 0.92. Providing emergency supplies alone did not yield better results than other measures. The main effect of these interventions comes from on-site education and home modifications, so the benefit of supplying emergency supplies is rated as “moderate” rather than “significant”. When buying fire extinguishers, look for the CCC certification mark; for pre-pressurized extinguishers, make sure the pressure gauge needle points to the green zone. Details on smoke alarms and carbon monoxide detectors are covered in section 3 of this chapter. Instructions for using tourniquets can be found in section 13, item 12. Guidance on how to select, store, and replace each item can be found in [docs/.md](../../docs/research/.md).

26. 备齐灭火器、灭火毯、逃生呼吸面罩和急救包,每年检查一次

成本: 灭火器、灭火毯、每人一只呼吸面罩,再加一个急救包,一套几百元。买一次就行,以后每年花十分钟检查一遍。

说人话: 灭火器、灭火毯、逃生面罩、急救包,都在应急管理部那份 11 样的家庭应急清单里。一套几百元,买一次就行。上门做过家庭安全指导的那些研究里,伤害发生率低约四分之一。

收益: 应急管理部的《全国基础版家庭应急物资储备建议清单》一共 11 样。其中「灭火器和灭火毯」用于「初起火灾的扑救」,清单还写明「灭火毯可披覆在身上逃生」。「呼吸面罩」指的是「消防过滤式自救呼吸器,用于火灾逃生使用」。「外用药品」是「止血粉、止血贴、纱布绷带等,用于处理伤口」。Cochrane 把 98 项研究、2,605,044 人合起来一起算。家庭安全干预让伤害发生率降到 IRR 0.89。可信范围是 95% CI 0.78 到 1.01。其中上门开展的干预,伤害发生率低约 25%(IRR 0.75,95% CI 0.62 到 0.91)

备注: 争议。同一份 Cochrane 汇总里,不发装备的那一类干预,受伤率低约两成。原值 IRR 0.78,可信范围 95% CI 0.66 到 0.92。发了装备的那一组并没有做得更好。降低伤害的主要是入户教育和改造,所以装备的收益记「中」,不记「大」。买灭火器认准 CCC 标志,贮压式的指针要停在绿区。灭火毯多是玻璃纤维的,只抓那两根拉带,别光着手摸毯面。拿它盖油锅也有争议:荷兰监管机构 2014 年测了 22 个牌子,按普通人的用法没有一个能稳定扑灭。油锅着火先关火、盖锅盖。烟雾报警器和一氧化碳报警器见本节第 3 条。止血带的用法见第 13 节第 12 条。每样东西怎么选、放在哪里、几年换一次,见 [docs/家庭应急装备清单.md](../docs/家庭应急装备清单.md)
