On a large project, safety is somebody's job. On a house, a maisonette, a four-unit block, it is nobody's job in particular, which usually means it is the owner's job, whether or not they know it.
The costly part of site safety is rarely the equipment. It is that nobody decided anything before work started, so every decision gets made at speed, by whoever is holding the tool.
Decide these before the first delivery
- Who is in charge on site, by name, every day. Not "the fundi" collectively. One person who can stop work, and who everyone knows can stop work.
- Where materials go. Sand, ballast and blocks stacked away from the working edge and away from where people walk. Most of the small injuries on small sites are trips and falling material, not dramatic accidents.
- How people get up and down. A proper ladder or a built stair, secured. Improvised access is the most common serious risk on a small build and the cheapest to remove.
- What happens to an injury. Where the first aid kit is, who has a vehicle, and the nearest facility that can handle a cut, a fall or an eye injury. Write the details somewhere on site.
The basics people skip
Helmets and boots for everyone, including visitors. The owner walking round on a Saturday in sandals is exactly who gets hurt, because they are the one not thinking about what is overhead.
Eye protection for cutting and grinding. The single highest-consequence, lowest-cost item on any site. A pair of goggles costs less than one clinic visit.
Edge protection on anything raised. Any slab edge, stairwell opening or first-floor perimeter that someone can walk off. Temporary is fine. Absent is not.
Keep the site tidy at close of day. Nails, offcuts, exposed reinforcement bars, open excavations. Ten minutes at the end of each day removes most of what injures people at the start of the next one.
Lock it, and think about who else can get in. Children get into unsecured sites. An open excavation or an unsecured stack of blocks is a serious hazard to someone who was never working there.
Water, power and the two that get forgotten
Temporary power on a wet site deserves a real distribution board and cabling kept off the ground, not a socket extension running through a puddle. And if anyone is working in a trench deeper than chest height, the sides need support. Collapses happen in ordinary soil, without warning, and they are not survivable for long.
Write down what happened
Keep a simple site diary: who was on site, what was done, deliveries received, and anything that went wrong, including near misses where nobody was hurt. Near misses are free information about the accident you have not had yet.
It also has a second use. A diary of attendance and deliveries is the same record that tells you where your money went, which is why cost control and site safety tend to improve together: both depend on somebody writing down what actually happened on the day it happened, rather than reconstructing it at the end.
None of this is specialist. It is a morning of decisions, a modest shopping list, and the habit of ten minutes' tidying at close of day.
What the law expects, briefly
Small sites tend to assume safety law is for large contractors. It is not written that way. The Occupational Safety and Health Act applies to workplaces generally, and a construction site is a workplace whoever owns it; the Work Injury Benefits Act puts the cost of an injury at work on the employer, which on a directly-run self-build frequently means the owner rather than a contractor.
Three practical consequences worth knowing before the first delivery:
Insurance is the control that matters most. Confirm in writing who carries workers' compensation cover and public liability for the site, and see the certificate rather than being told it exists. If you are engaging fundis directly rather than a contractor, assume the exposure is yours until a document says otherwise.
Use a registered contractor where one is required. Contractor registration exists so that somebody with accountability is running the works, and it is worth confirming at the quotation stage rather than after an incident.
Approvals are a safety document, not a formality. County approval of the plans, and the structural design behind them, are what stand between a cost-saving decision on site and a slab that does not hold. A change made on site that departs from the approved drawings is a safety decision even when it is presented as a cost decision.
The five that cause the serious injuries
Small-site incidents cluster tightly. Nearly all of them come from this list:
Falls from height. Improvised access, an unsecured ladder, an unprotected slab edge, a stairwell opening with nothing across it. This is the largest category and the cheapest to fix: proper ladder, tied at the top; edge protection on every raised edge; openings covered and the cover fixed down so it cannot be moved and forgotten.
Falling material. Blocks stacked too high, tools on a scaffold board, material passed up rather than hoisted. Helmets are the last line, not the control. The control is that nothing is stored or left at an edge.
Trench collapse. Any excavation deeper than chest height needs the sides supported or battered back. Ordinary soil collapses without warning and a person buried to the chest cannot breathe against the weight. This one kills people on small sites specifically, because a house's drainage and foundation trenches feel too routine to be dangerous.
Electricity. Temporary supply through a proper board, cables off the ground and out of water, no improvised connections, and one person responsible for the temporary installation. Wet sites and extension leads are a recurring, fatal combination.
Eyes and hands, from cutting and grinding. The highest-frequency injuries and the cheapest to prevent. Goggles and gloves, on site, in a box, replaced when they are lost rather than shared.
A safety routine that costs ten minutes
Safety on a small build fails through inconsistency, not ignorance. The routine that holds:
- Before work starts: one person named as responsible each day. Access, storage and the injury plan decided. First aid kit on site and stocked, with the nearest clinic's location written where everyone can see it.
- Each morning: two minutes with whoever is on site: what is happening today, what is overhead, what is open. Not a lecture. A list.
- Each evening: ten minutes tidying. Nails removed or bent over, offcuts cleared, exposed reinforcement capped, excavations covered or fenced, tools away, site secured against children.
- Each week: walk the site specifically looking at edges, access and the excavation. Write what you found in the diary, including what you fixed.
The site diary earns its keep twice
Keep one book: attendance, weather, work done, deliveries received, instructions given, incidents and near misses. It takes a few minutes at close of day.
Its second use is financial, and it is the reason this article sits in a series about cost control. Attendance is labour cost. Deliveries are material cost, and the same entry supports the goods received note your budget depends on. Instructions given on site are usually variations that nobody priced. Weather is the evidence behind a programme delay.
A site that writes down what happened on the day it happened gets both a defensible safety record and a build whose costs can be reconstructed from something better than memory. Sites that keep neither tend to discover both problems in the same month. The same discipline scaled across several projects is what construction cost control software is for: the daily site record, the material received, the labour posted and the budget position in one place rather than in four notebooks belonging to four foremen.
Common questions
Who is responsible for safety on a small site in Kenya?
The employer, which on a contractor-run project is the contractor and on a directly-run self-build is usually the owner. Establish in writing which it is, and confirm the insurance behind the answer, before work starts rather than after an incident.
What safety equipment does a small build actually need?
Helmets and boots for everyone including visitors, eye protection and gloves for cutting and grinding, a stocked first aid kit, edge protection material, proper ladders or built access, and secure fencing with a lockable gate. The total is small next to a single serious injury.
Do I need insurance for fundis working on my house?
Assume yes. Workers' compensation cover is what stands between an injury on your plot and a liability you fund personally, and the answer should be a certificate you have seen, not a reassurance you were given.
What should I do if there is an accident on site?
Get the person to care first; the plan for that is decided before work starts, not during. Then record it: what happened, when, who was present, what was being done, and what has changed since. Record near misses the same way, because they are free information about the accident that has not happened yet.
Is a site diary really necessary on a house?
It is the cheapest document on the project and it does two jobs. Safety-wise it is your record that hazards were found and fixed. Financially it is the attendance, delivery and instruction record your final account depends on. See how to budget for building your own house.
Does any of this slow the build down?
Tidying takes ten minutes a day and access built properly takes an afternoon once. Against that, the events this prevents stop a small site for days or permanently. The builds that lose time to safety are almost always the ones that had not decided anything in advance.
