Hi
OK, you have to be extremely careful with pigeon mess.
You will need full PPE, that is chemical suit, full respirator,safety wellies, all cuffs must be secured (use tape) you will need dense rubber gloves, plus another latex pair underneath, you should also plug up your ears.
You will also need Bio hazard refuse sacks as the pigeon guano is a bio hazard and MUST be incinerated.
Pigeon Guano carries around 60 diseases, of which 40 are communicable to humans here are a few:
Cryptococcus:
Health Effects. Clinical manifestations of pulmonary infection are not characteristic and may be absent. The infection may disseminate to the central nervous system, resulting in cryptococcal meningitis (inflammation of the membranes of the brain and spinal cord), which is difficult to diagnose and fatal if not properly, and promptly, treated.
Histoplasmosis.
Most infections produce no symptoms or only a mild influenza-like illness. However, pneumonia, blindness, and even death from a chronic infection are possible.
Psittacosis:
Psittacosis is characterized by fever, headaches, and muscle pain, with or without obvious respiratory symptoms. Untreated cases, especially in older patients, can progress to pneumonia and/or generalized toxaemia resulting in death.
Viral diseases:
HerpesVirus
CircoVirus
Avian parvovirus
Avian reovirus
Eastern, western & Venezuelan Equine Encephalomyelitis
Rubivirus
Bacterial Diseases: Fungal diseases:
Staphylococcus Candida
Streptococcus Microsporum
Myobacteria Aspergillus
Listeria Trichoderma
Clostridia Pigeon Fleas
Salmonella
Enterobacter
Psuedomonas
Aeromonas
Vibrio
Actinobacillius
Haemphilus
Chalmydia
Ricketsia
There are also parasitic diseases (flies and flesh eating maggots)
I would not pressure wash it at all as there will still be residue present and this will splash everywhere.
You will need a bactericide which you will pre-spray and you must leave on for at least 15 mins before work begins.

Martin
