Funny enough my insurance said home mix is fine red label with surfactant added at homeIt's only hypo with their own surfactant added
If worried mate buy 1 drum and use that for all your home made mixes
Any issues show them the benz drum you are " using" :1f602:
All sorts of interesting information hidden in MSDS/ SDS sheets once you know what to look out for. :1f609:I prefer to keep hydroxide and hypoclorite seperate as they have different uses for me
Hydroxide on wooden fences etc and hypo on concrete, render etc
Hydroxide i find is a bit kinder to wood (or sodium percarbonate if i have time to take on the job)
Didn't realise they had mixed both in blackwash
Sodium Hydorxide improves the effectiveness of Sodium Hypochlorite and is the other main ingredient in blackwash. It does also contain a surfactant.
Who are you with for insurance Tench? I need to get on board with them.

With a lot of this stuff it's not a problem until something goes wrong and there is a claim. Then they are looking for any reason to not cover you. I must admit I must have used about 4000l of farm hypo last year but it is always worth knowing exactly where you stand on the legal and insurance situations.
The SDS sheet is there should something go wrong so that people know how to treat it not to give you an exact breakdown of ingredients and concentrations and only covers the potentially hazardous components.That doesnt make good reading does it 5-10 % consentration is a big difference.
Sodium hydroxide in 0.5 % is not going to do a lot when you then dilute it to there recommended rate , I personally think it’s a gimmick to get you to buy the only approved hypo cleaning agent : at a grossly exajerated price but I guess a lot must buy it as they are still in buisness , by doing a bit of reaserch it’s easy to make your own far cheaper that will do just as good a job , but it’s up to everyone to make up there own minds what they want to use just think that Benz play on the scare factor to get the less informed to buy there product : cost wise I cannot see any decent sized company buying it as it’s to expensive to use most big firms I know buy hypo in 1000 ltr ibc tanks and mix there own , Ime not knocking Benz products as they do what they say on the tin but it’s just way to expensive for what it is and people need to know that
Accidents happen to everyone. Splash in the eye, soaked through gloves, leaking fitting on the pump that pops off while under pressure at exactly the wrong moment.What can can go wrong ? If used according to the mdsa data sheet you are fine been using it for years never had a problem but you do have to be careful with it especially when mixing it
I know as I am a bit of a chemist when it comes to mixing chems for different purposes but never read the sheets for blackwash as never used it as I prefer to make my own mixAll sorts of interesting information hidden in MSDS/ SDS sheets once you know what to look out for. :1f609:
I wouldn't say the same results at less concentration as I would only use a certain percent mix for a specific job whichever make I usedAccidents happen to everyone. Splash in the eye, soaked through gloves, leaking fitting on the pump that pops off while under pressure at exactly the wrong moment.
If COSHH is applied when using hypo strictly speaking benz is better because it can achieve the same results at lower concentrations with less hazard and risk to the applicator (person) and the environment.

This is why the hydroxide is added. It does increase the effectiveness at lower concentrations. So Benz might do at 1% total Sodium Hypochlorite what regular hypo would do at 2%. Also the surfactants "keep it wet" longer allowing for alonger dwell time further reducing the need for a stronger mix.I wouldn't say the same results at less concentration as I would only use a certain percent mix for a specific job whichever make I used
Blackwash at 10:1 for a 1% mix I think it is has the same active hypo as swimming pool hypo and surfactant mixed to 1%
Appropriate ppe needs to be observed for each job to minimise risks also

Everyone can make a mistake. Just giving examples of what could happen. Those are all examples I have seen on some of the US groups most of which would never happen to us or anybody with the right knowledge and application of that knowledge. A lot can be avoided by using the correct PPE etc but nothing is 100% perfect without a perfect operator 100% of the time.As i as I said if using the correct ppe splashes in the eyes will not happen if using the correct ppe
soacked through gloves ?.. how the gloves we use that’s impossible as we use gauntlets that are resistant to it and water proof cannot happen
fittings under pressure ?.. why are you near them whilst using the stuff sounds like very poor use of of equipment or the wrong equipment being used again in goggles and or face shield are used cannot happen
