Is "Safety First" the right mantra for parenthood? As a parent in rural Hong Kong I had to weigh the risks of letting my daughter roam the village in bare feet, oh yes, and hanging out with 1000 pound feral water buffalos!

Creating a safe learning environment is the most central concern here at Mobile Mini Class. This starts with the design of the classroom itself. It has fours doors distributed on three sides, with an emergency exit window on the forth side. Copying the delivery drivers, from my time living in Tokyo, the wheels are chocked before children arrive, in case of brake failure or earthquakes! It is fitted with smoke and carbon monoxide detectors, and fire extinguishers. The main stairs are 40 inches wide and built at an extra gentle angle. However accidents happen and so do children. No space can be guaranteed 100% risk free.
The classroom is primarily a STEM lab and workshop and as such, contains many obvious risks such as, scissors, knives, hot glue guns, soldering irons, woodworking tools etc. My personal ethos is that it's better to teach even very young children to recognise and respond wisely when they open a drawer and find a sharp knife, than assume the knives are out of reach. However, that said I do organise the space so that immediately dangerous objects such as knives are closed away out of reach and only used under appropriately close supervision.
If a potential course could include the use of tools beyond basic paper cutting scissors, parents will be invited to discuss their comfort levels with various tools and scenarios. My own experience with Forest Kindergartens and also with my own children is that if we reduce to zero the odds that a child will never need a couple of stitches during their first 18 years, then we have probably ruined childhood as we knew it. However, most of our courses are based around materials and resources that limit the use of sharp blades and hot glue for example. But some of the courses, such as how to design and build your own Radio Controlled Aeroplane out of foam board are entirely dependant on sharp blades and hot glue. As students progress into their third or forth term with MMC they may be safely clipping together advanced EV3 robots or they may be skinning their knuckles, stripping down a washing machine to invent a new electric wheelbarrow. Potentially the only limits are the children's imaginations, their parents tolerance of risk and the quality of my liability insurance and liability waiver.
