The SPCA has also noted the  Explosives Act No 26 of 1956:

“This law applies nationwide with no exceptions. It is unlawful to discharge any firework in any building, on any public thoroughfare or in any public place or resort without prior written permission of the local authority. (Section 10.34). Section 10.35 relates to public displays of fireworks and states that no person may do so on any premises without the written permission of the Chief Inspector of Explosives (commonly known as “having a permit”). This written permission will stipulate conditions and any non-compliance with them is a criminal offence. In terms of the Explosives Act, no person shall allow or permit any children under the age of 16 to handle or use fireworks except under the supervision of an adult person. This Act is enforced by the South African Police Service (SAPS) not by the SPCA. Please report any offences to your nearest SAPS, giving as many details as you possibly can and quoting the Act name and number plus the relevant section as given above. IGNORANCE OF THE LAW IS NO EXCUSE – PENALTIES ARE SEVERE. DO NOT BE AFRAID TO REPORT OFFENDERS.”
